If life is best measured by the adventures you take and the people you love, then Daniel James O’Leary lived a life larger than most. Dan passed away suddenly on April 5, 2025, leaving behind a trail of unforgettable stories, beloved family, and the kind of legacy only the most generous spirits can leave.
Dan was born on March 13, 1968, in Helena, Montana, to William and Lucille O’Leary. He grew up in a joyful, close-knit home alongside his siblings and first friends; Michael, Kathleen, Maureen, and Janet, where days were filled with outdoor adventures and family stories told around the dinner table. His love for nature, people, and a good laugh took root early—and never let go.
After graduating from Helena High in 1986, Dan earned a degree in Engineering Science from Montana Tech in 1990, launching a successful career. Perhaps Dan’s greatest accomplishment during this time was the birth of his daughter, Katherine.
As a single father, Dan raised Kate with boundless energy, love, and unwavering presence. Dan loved that she was born a “Butte Rat”. After long days of work, he’d coach her soccer games, make dinner, help with homework, and still have time for laughter. Through him, Kate learned his love of the Irish, how to pray, the importance of family, and so much more.
Dan’s career took him from Montana to Alabama, and then to Washington, where he continued his work as an engineer—first with CH2M Hill, and later with Jacobs Engineering. He approached every project, big or small, with care and quiet pride, forging friendships that lasted decades.
In 2010, Dan married the love of his life, Cynthia, and together they created a partnership full of adventure, laughter, and deep affection. Cindi was his balance—his “yes” to every wild idea, camping trip, or backyard project. Whether floating the Smith River, hosting friends in their lovingly restored Helena Victorian, or gathering around the table for a meal made from scratch, Dan and Cindi made life beautiful and full.
His love for the outdoors was as endless as the Montana sky. He kayaked through the San Juans, cycled hundreds of miles—including a 800-mile ride across Spain with Cindi —and ran four marathons, finishing his final Marine Corps Marathon in D.C. with his best time, no training, and a smile. He backpacked through Machu Picchu, floated remote rivers, and hiked to the best huckleberry patches, always bringing others along for the ride. Dan believed life was meant to be experienced, and he brought joy to every mile.
He had a hearty, contagious laugh, a knack for storytelling, and a habit of pulling everyone into the fun. Whether tinkering in the basement with the boiler, debating arc welding techniques, or helping a neighbor fix a fence, Dan was the guy you called—and the guy who always showed up.
He loved his daughters Kate, Amanda, and Amber. Whether biological or chosen, they were his girls, and he supported each of them through life’s highs and lows. He delighted in being “Papa Dan” to McCoy, Finnian, and Bette—his face lighting up whenever they were near.
Dan was the guy who would help you wire your light fixtures, teach you to fish a stream, and then crack a beer and ask how your week was. He served on ski patrol, took care of his neighbors, and brought people together. The Halloween parties at the O’Learys’ home became legendary—not just for the costumes, but for the joy and inclusion Dan cultivated.
Dan was a man of deep Catholic faith and a member of the Cathedral of St. Helena. He believed in the power of prayer and the importance of taking care of each other. He was a man who reminded us—often with a that quick grin of his—that “The good Lord looks out for dumb Irishmen,” and he meant it because often it followed a situation where good Irish luck had prevailed.
Dan’s favorite expression was “Keep the faith”, an expression he learned from his father, William whom he loved deeply and preceded him in death. He is survived by his wife, Cynthia; daughters Kate (Jordan), Amanda (David), and Amber (Juan); grandchildren McCoy, Bette, and Finnian; his mother Lucille; siblings, nieces, nephews, cousins and a village of people lucky enough to call him a friend.
In honor of this man who left us far too soon, live your life like he did. Pick up a new hobby. Say yes to an adventure. Float the river. Ride the bike. Help your neighbor. Tell a story. Laugh. Pray often, love your family and greet one another with a smile—because Dan always did.

Dan brought a calm manner and warm heart to the Ski Patrol family. He was generous and kind. My deepest condolences go out to his family. I am thankful for the times I spent carpooling, skiing, patrolling , and chatting with Dan.
He will be greatly missed and forever loved.
Cynthia Murray says
Dan was a hard working, diligent, creative, and customer-focused professional. We are so sad to hear this news and will miss him greatly. Our prayers go out to his family, co-workers, and friends. In peace,

I met Dan 29 years ago through my wife, when they worked together at CH2MHILL in Montgomery, Alabama. From the moment we met, we hit it off. He invited me on backpacking trips and over the years our bond grew into a deep friendship. So much so that he became the godfather of our sons. Dan was a man of true honor and integrity. I am thankful for having him in my life. He will be deeply missed and forever loved by our family.
Tina & Ron Hastings says
It must have been 20 years ago when we met Dan after he moved to Washington. He had a way of drawing people together and making everyone feel at home. We had many get-togethers, and laughs, and occasionally some excellent Bolognese. Dan had a big, kind heart, and we will miss him.
Jennifer Baldwin says
I’ve gotten to know Dan over the years as co-workers, and we really talked regularly since 2020. I considered Dan a friend even more than a co-worker, and that was how he was. Dan connected people and really cared about everyone that he talked to. I will definitely miss our conversations, especially the random Friday afternoon calls! My prayers go out to all of his family and friends.
Tom Williams says
I am so deeply saddened at Dan’s passing. Dan was an exemplary individual. I feel honored to have known him. He was a colleague and friend. His professional knowledge and experience will be missed by many including me. I will sorely miss his kindness, generosity, and care. There are many stories he was going to finish “over a beer” one day. I regret I’ll never hear those stories or meet any of the pageant of people in his life that he was sure that I would adore as much as he did. We all have to say goodbye too soon with so much left unsaid. . .
Hong Zhang says
I just can’t believe this. I came to Seattle 15 years ago, and worked on a hydraulic modeling project, which Dan was leading. He taught me presenting skills and invited me to a canon ride with other friends. I still remember how happy he was in his wedding and how impressive his bike skill was on the west point hill. RIP. You will be missed!
Joseph Pang says
I knew Dan several years ago when he was working in the Seattle area. He was a very nice, humble, and welcoming person and professional. Professionally, I was impressed by how detail oriented he was. He could notice and bring up issues that everyone had missed which helped to resolve the issues at hand. Outside of work, even though I didn’t know him for a very long time, he invited me to kayaking with him and another colleague on Lake Washington for a few times and he invited me to his wedding. He even invited me to Montana if I had a chance to go over there. Dan IS a great person and he will be greatly missed. Dan, have fun kayaking with Jesus Christ our Lord up in heaven. We will see each other again and we can kayak together again, but this time with Jesus too!
Rick Ahmann says
Since the 7th grade, my friendship with Dan is one I truly cherish. While equally busy in our lives, we have always been able to simply pick up again right where we left off. Our common Catholic Faith encourages us that this earthly life is just a pause and what helps to lead us to eternal reward. His fervent faith, constancy to family and friends, generosity of spirit and his deep love for Cindi are all examples to follow in seeking the best this life can offer. Dan was never out for himself, but rather shared of himself completely.
O’Leary Family – I pray for your peace in this challenging time. I’m grateful our paths are intertwined! While Dan was always crafting a list of things to do next and working to make complex things more simple, this loss doesn’t fit so neatly. This is a time to lean into the Father and trust in Him.
I miss you already dear friend. May God grant you Eternal Rest.
Mike Eiselein says
Such a shock to hear of Dan’s passing. My wife and I just visited with him and his mom as they were passing through Kellogg recently. Every encounter with Dan was always full of laughs and reminiscing of the “good old days”. Our friendship goes back to our time together as Montana Tech students where Dan was my roommate for a couple years as well as a fellow RA with my wife in the residence hall. The shenanigans we either started or were a part of could fill volumes! He was an enduring friend over the years and was always better at staying in touch than I was. Dan enriched the lives of everyone he encountered, as evidenced by the shared memories here. We all know what a devoted family man and friend he was. Such a loss for his family and our prayers are with you all. He will be greatly missed. See you on the other side, brother.
Bill McMillin says
I’ve known Dan as a great engineer, a great friend, and truly a good person, for many years dating back to my early days at CH2M Hill 20 years ago. Dan was always there for all of us at CH2M/Jacobs to help out with a soft-spoken manner. I always felt better after talking to Dan. I will miss him terribly. God bless and keep you, Dan.
Barry Mr Walton says
What dreadful news. I met Dan with the Storbo family when we were planning a hike from Stevens Pass to Canada years ago. Dan participated in the logistics of and early stages of the walk and we kept in touch over the years after that. We managed to get together for a canoe trip on the Missouri in Montana after the PCT and had an untidy prospect of meeting up with Cindy and him on this side of the pond.

Steven Drangsholt says
My condolences to Dan’s family and friends for his sudden loss. Dan was a humble, kind and generous man. I appreciated his smile and easy going approach to working together over the years. Dan had something about him that told you “everything will be okay” even as the task was driving off a cliff. Working with Dan early in my career, he taught me about the value in asking good questions and staying curious. Dan will be missed but he has an important legacy that lives on.
Floyd Darmon says
Dan was a great friend and co-worker at CH2M and now at Jacobs. I already miss him! Our first project together was more than 20 years ago in Kodiak, Alaska and more recently on work down in Ketchikan, Alaska. We were recently in Ketchikan together to help the City solve some of their infrastructure problems. Dan was certainly one of the “good guys” and always was a #1 contributor to our projects’ success. I will very much miss his friendship, great sense of humor, and his “war stories” about the fun had on so many successful project.
Brian Lannan says
This was devastating news, fifty-seven years – it feels far too short a time for a man who brought so much life and laughter to everyone around him. Dan wasn’t just a neighbor; he was a true friend. He was the kind of person who always had a smile and a wave, ready with a helping hand or a listening ear. Whether it was lending a tool, sharing a story over a beer, dropping by a fresh loaf of bread, or just offering a friendly hello, Dan made our neighborhood a warmer, more connected place. As a friend, Dan was loyal, supportive, and just plain fun to be around. He had a knack for making even the most mundane moments feel brighter. The absence of his presence will be felt by all of us who knew him. The neighborhood won’t be quite the same without him. Though his time with us was too brief, the impact Dan had on our lives was significant. He reminded us of the importance of community, friendship, and living each day with a generous spirit. We will carry his memory in our hearts, cherishing the moments we shared and striving to live with the same kindness and warmth that Dan so effortlessly embodied.
Rest in peace, dear friend and neighbor. You will be Greatly Missed.
Uri Papukchiev says
Dan met me at the construction site just a year ago. The work was intense, where we worked on a Client facility near San Francisco. We worked remotely and met only once on video camera. Over multiple Teams calls with Client, Contractors, and other Engineers, Dan demonstrated that he was bigger than his narrow field of hydraulics modeling and civil engineering. He beamed the light of a genuinely good human being. With a calm and warm-hearted voice timbre, he led us toward mutual agreement. I still remember the modesty of his voice when he admitted the completion of his last annual ski patrol assignment.
As we go along with our career in life, we meet the opportunity to become good to other people. It is not that we are technically more capable, but rather that we are truly good people. I saw Dan O’Leary not just a superb professional. He showed me how good a human being he is.
To his family, I am sending my most sincere condolences. His path in life ended way too early. Through wisdom, he found true purpose and destiny.
Dan, You are dearly missed and respected. A distant hug and eternal peace from a fellow engineer.
Ryan Dunne says
Dan was introduced to me as a technical advisor early in my career and at first I figured he was so kind and supportive due to our shared heritage and fondness for large gassy dogs. It didn’t take long to figure out that he found something in common with just about everyone and was just as kind even if he didn’t. He was one of the people I’d introduce new employees to when I had the chance because I knew he’d make them feel welcome and would know at least one other person they should meet. He was a strong, humble, funny, endearing, and generous guy through and through.
Like others have mentioned, I regret not getting a chance to hear the ‘someday’ stories that were promised. While relatively short, I greatly appreciate the time I did get to spend with Dan and all of the memories and details everyone is sharing here that reflect the depth and breadth of his legacy.
My condolences to his family – he talked often and very fondly of you.
Art and Sharon Storbo says
Dan was a true friend with a great work ethic at CH2M-Jacobs, a much-loved adventurer, always full of fun. Dan, his wife Cindi, my wife Sharon, and I had fine times together. Dan, a Norwegian cousin of mine, a British friend, and I hiked the toughest section of the WA Pacific Crest Trail together in 2006 (Boulder Pass, Napeequa River valley, and Little Giant Pass). In following years, Dan, Uncle Joe, Sharon and I made canoe trips down the Missouri River from Ft Benton to Judith Landing with numerous side trips: hiking, enjoying fantastic scenery, Montana geology and wildlife, Lewis and Clark history and campsites, and stunning night-time skies. Following my retirement, we frequently talked of other adventures yet to do, but now this is not to be. Luckily, we have pictures and the memories to remind us of the good times we had together. Rest in peace, dear friend, until we meet again on the trail. Our thoughts and prayers are with Cindi, Dan’s mom and the rest of the family.
Dianne Staloch says
Dear Cindi our wonderful friend.
Words can’t express the sadness that we feel that Daniel is no longer on this earth. He was such an amazing man. So loving, kind, fun, generous, always ready to help anyone in need. He loved and adored you Cindi, and it was wonderful to see that love he had for you!
We will miss him forever and he will forever be in our hearts.
We love you, Cindi
Dianne and Warren
Stephen Bianchetta says
So sad to hear of Dan’s passing. I first met Dan about 10 years ago working on a program in San Mateo. Dan was so easy to talk to and was just an overall great guy and a lot of fun to be around. Rest in peace Dan! You are missed. My thoughts and prayers go out to Dan’s family.
Patrice Staloch says
Dearest Cindi,
There are no words.
Just love for you as you bear the unbearable loss of your sweet Dan.
The times that i was fortunate enough to be in both of your presence
are treasured. Those are lovely memories.
Love to you.
Patrice
Ashish Sharma says
So sad to hear of Dan’s passing. this sudden loss is unimaginable. my heartfelt condolences to the family. I’ve had been working with Dan remotely from India for almost a year now. he was a great guy & he would always make the environment welcoming & friendly. he was great at his work & would always appreciate other’s efforts as well.
Phil Martinez says
What a shock! I hadnt spoken with Dan in a few years, but we always had a few laughs and swapped a few stories back in the day when he lived in Western WA. He was always, go, go, go, and had something fun going on………and was always upbeat and optimistic. We worked together a bit, but went running together several times. I could keep up with him…..but barely…. He loved being back in Montana. His family is in my thoughts and prayers.
Ken Sargent says
Cindy and all the O’Leary Clan. I am heart broken at this news, I just couldn’t believe what I was hearing when Kathy called the other night. I don’t have the words to express my sorrow. Dan was there for me when we lost Scott and I am here for you all if there is anything I can do. We go back 40 plus years and I remember the smiles, the laughter and the hijinks. Can you all imagine the hijinks he and Scott are up to in heaven right now?!?! Dan was a good man, one of the best I have ever known and he will be missed by all the Sargents. My prayers and positive thoughts are with all the O’Learys in this sad sad time.
Cindy Galbavy says
Dan was an amazing man who I met teaching at HHS Adult Ed Welding. He was a very kind sole and just a joy to see. I am so sorry for your loss. Our community lost an amazing man. He was one of our biggest supporters for CTE world. He will be missed by everyone who knew him. Deepest Sympathy
Susan Moisio says
I got to know Dan through working at CH2M Hill and learned so much from him. He was a very calm, thoughtful person who I counted on for technical guidance and for leadership for our folks around the world. He will be missed.
Chris Dinsmore says
Like many, I was fortunate enough to get to know Dan through work. Also like many, I realized that he had transitioned into a friend versus a work colleague in very little time. While Dan’s technical abilities were significant, they paled in comparison to his greatest skill – his willingness to give others his time. I’m going to miss chatting with him about everything and anything (though rarely consistently about the actual topic at hand). My condolences to his family and friends. Dan’s going to be missed.
Daniel Buonadonna says
Dan was always friendly, ready to help, and humble. He was an important member of our, “work family” and I pray that he may find peace. My sincere condolences to his loved ones.
Brian and Ginger Knox says
Dan was such a wonderful person. Any time we caught up with him it seemed like we chatted yesterday, even though it could be months. We would stop by on our cross Montana trips to enjoy a wonderful evening of food and drink with Dan and Cindi. They always made time for us and we had a good laugh (even the time they discovered our dog snuck away and ate all the cat food). Each time we would make plans for things to do in the future. Dropping in for fly fishing, visiting the plains with a dog or two, taking a canoe trip. Each year we put it off for the next year because there always seemed to be more time. Our sympathies to Cindi and the family.
Perrin Niemann says
My deepest condolences to Cindi and the rest of Dan’s family; I am praying for you all. I had the pleasure of working with Dan for over 25 years and enjoying every minute of it. He was a valued colleague, but more than that, he was a true friend. Any day that I got to talk with him was made better by it. Our conversations always took too long, were sprinkled with stories, and were full of laughter. He was always willing to commiserate with me, but somehow those conversations took on an optimistic spin. I can’t believe I have to work without him now. It wasn’t long enough, but something tells me it never would have been.
Helen Lu says
I knew Dan from my first sewer modeling project after joined CH2M more than 15 years ago, and we were like modeling buddy since then. We never met in person after all those years with CH/Jacobs, but he is such great friend, always there as I needed support or just a laugh. He likes saying “try to stay out of trouble” “don’t work too hard and have a life” or “just grab a beer”…… I still have a reminder on my calendar to check back with him on his upcoming trip to Atlanta in mid of April and try to plan sth to catch up, just can not believe it…. Dan, my friend, you will be deeply missed!
Russ Barton says
Dan was bigger than life. His stories — true stories — were better than anything most of us could make up. He was kind, funny, energetic, and hard-working. His optimism was contagious. I fondly remember working with Dan as both a colleague and a client. Those who knew Dan knew how much he loved his family.
Dan, you are missed. I celebrate your life. I expect to hear from you soon about the great rivers and trails where you are. Godspeed my friend.
Dennis and Carol Hanson says
Wow. What a shock. We are so sorry and saddened by the lose of our friend. Dan leaves behind many great memories of his kindness to others and desire to have fun. Our hearts go out to Cindy, Joe, Barb, and the rest of the family. Love you guys!
Brady Fuller says
Dan and I worked together in Seattle area starting in 2001. I always enjoyed sharing plans and stories from river paddling trips we had each taken, and most recently had communicated with him as I was looking at a float trip on the Missouri River with my family. Thanks for being a friend, Dan, and for your positive outlook and care for those around you.
Dr. John and Victoria Cech says
On behalf of the Carroll College community, the Board of Trustees, my wife Victoria, and myself, I extend our deepest condolences to Kathleen O’Leary, Janet Johnson, and the entire O’Leary family as you mourn the unexpected passing of your beloved brother, Daniel James O’Leary.
During this time of profound sorrow, we join you in prayer and solidarity. May the peace of Christ, which surpasses all understanding, guard your hearts and minds (Philippians 4:7). We entrust Daniel’s soul to the loving embrace of our Lord, confident in His promise of eternal life through the Resurrection. As Catholics, we find comfort in knowing that “Blessed are those who mourn, for they shall be comforted” (Matthew 5:4).
May God’s grace sustain you in the days ahead and may the cherished memories of Daniel bring consolation amidst your grief. Please know that you are surrounded by the prayers and support of the Carroll College family during this difficult time.
Eternal rest grant unto him, O Lord, and let perpetual light shine upon him. May his soul, and the souls of all the faithful departed, through the mercy of God, rest in peace. Amen.
Pat and Cindy White says
When I joined CH2M Dan became my Colleague, On day two we became friends. Cindi and Dan welcomed my Cindy and me into there home and lives. Such a caring insightful warm and outgoing person we will never meet again. Dan’s personal and professional conduct was of the highest caliber, and I will forever look up to him. Through remote chats at work and around not enough camp fires, a deep friendship grew . We will always miss you my friend. Cindi we are always here for you.
Quitterie Cotten says
Dan was one of a kind in so many ways. We worked together on several projects at Ch2mHill/Jacobs and I always appreciated how positive and solution oriented he was. He was grounded, sharp, patient and a great relationship builder. He was a mentor to so many of us at Jacobs. We became friends over the years, and it was always a better day when I got to reconnect with Dan. He was generous of his time in helping family, friends and colleagues alike – a tremendous human being all around. My deepest sympathies to his family. Dan will be deeply missed.
Shad Roundy says
Dan was an early mentor for me in my career and over the years we had continued to talk several times a year. In our conversations, he was always cautious to balance business demands with personal goals and life perspective. I really appreciated his kindness. He will be missed and remembered often. My deepest sympathy to all mourning his passing.
Anna James says
Dan O’Leary was one of my favorite people to work with, and one of my favorite people to know. He and I met on a long term program in San Mateo years ago, and we worked really closely together for about 7 or 8 years. It is almost impossible to put to words how Dan was more than just someone I worked with; as many of our other colleagues have said, Dan was smart, kind, warm, and generous. More than that, he was someone who always remembered what you told him when you last spoke, he was someone who always noticed small changes and was empathetic to their causes. This made him excellent at his work, detail oriented and thorough, and it made him a wonderful person to have a friendship with. Dan was also funny – so funny – we had long running inside jokes that always made each other laugh, even when work was stressful or serious or urgent. He always used to make me laugh, and our calls always ran long.
I messaged Dan last week even though we aren’t working on a project together, I’m still not sure why I reached out. He responded, “Hi friend!!!!”, just like that, with multiple exclamation points, and I blew off my next call to chat on the phone with him for 16 minutes and I’m just so grateful that I did. Dan was always telling me to enjoy life, and to stay out of trouble, so I got to tell him that I started skiing (he was thrilled), and finally had been dating a nice Irish man (he was also thrilled). He said, “welcome to the good life” and it still makes me smile to think about how happy my minor life updates made him. That’s how Dan always was; his life’s work was the relationships he cultivated, the connections he maintained, and the celebrations of his friends and loved ones, always with enthusiasm, and always with a suggestion of more stories over beers.
Hoping one day I can cash in on all the beers we owe each other, the tab running up on both sides over the years. All my love to Cindi and his family, who he loved dearly and spoke of constantly with such love and esteem.
Court Harris says
“Yo, Danny Boy! What are you doing?”
“Court! Good to hear from you!”
Every call started this way with Dan. What was meant to be a 2 min call would inevitably turn into a 15 minute BS session that made us both late for the next meeting or call.
Dan has always been part of my career at Ch2m/Jacobs. The projects we worked on together are too many to count. Dan was my go to on so many things, and his patience and suffering of my impatience were so appreciated. So many late nights running modeling scenarios and side chatting about fishing, kids, dogs, wives, boats, fly rods, skis, trips, food allergies, you name it. Just an irreplaceable rapport…
The stories are many but here are a few classics:
THE NOISE. We were on a very important client call for a major program. Dan and I are both joined remotely from our homes in Montana. Dan is presenting his modeling results. Every 20 seconds a freight train noise cuts in on his voice feed. I am trying to figure out what the noise could possibly be. I side chat Dan, “Dude, what is that sound? Your mic may be jacked up.” “No Court. That is the dog. The dog is under my desk and she is snoring.” From that moment and for a long time while Giselle was still running around, her unmistakable snoring permeated many of our calls, always with chuckles. Our clients knew the O’Leary’s dog. Giselle was actually added to many meeting attendees list as “O’Leary’s snoring bulldog”.
FISH ARE A MYTH. Shortly after Dan and Cindi moved back to Helena, and after years of harping on him to get with the program and get a fly rod and a boat, he agreed to join me and another colleague (Nate from AE2S in Great Falls) on a float trip down the Missouri by Craig. Both Dan and Nate possessed the bare minimum set of skills and knowledge when it comes to fly fishing, and I didn’t trust either to row, so I captained and pretended to be the guide for the day. The beer and whiskey was also present. Wonderful fall day, great fishing forecast and good times ahead. I did my best to put them both on fish, back rowing to hit the good spots, tying on files and fixing their numerous bird nest casts, and I kept a beer in hand. I even brought lunch. After about an hour of watching futility in action, we reached a nice calm stretch. O’Leary leaned back (in the front seat), and decided to enjoy the view with a fresh beer in hand. Of course, since we were on the Missouri and there are never enough casts, I dropped anchor and immediately dissented – “What the hell are you doing Dan? This is a good spot, get yer fly back on the water.” “Court, there are no fish in this river. No one is catching anything. Fish are a myth.” “Dude, give me your rod.” (snicker and classic O’Leary eyebrow raise, hands me rod)… I took a few false casts from the rowing seat, laid the fly out on a nice riffle, and two seconds later, BOOM. Nice 16-inch rainbow. “Dammit Court, now you are making me feel bad.” I laughed for a good 2 minutes… “That’s what you get buddy!” Meanwhile, in the back of the boat Nate, sipping his beer and barely fishing, says, “Hey, I need the same fly. This one isn’t working.” Not satisfied with a second mutineer, I aggressively obtained Nate’s rod with some disparaging commentary, flopped it out the other side from O’Leary’s failure, and watched a nice brown surface and sip the fly. The fish gods were having a comedy show that day. Both were netted, photos snapped, and we moved on. There was no talking for at least 10 minutes after that. And when I asked to see a rod for the rest of the day, I was impolitely rebuffed by both with less than savory vernacular. It was a memorable day for sure, and my sides hurt from the laughter.
There was only one Dan O’Leary. An irreplaceable man. He set the bar unreachably high for being a son, husband, father, friend, coworker, husband, mentor.
To Dan O’Leary!
Cindi, you need anything anytime, just call and I will be there. – Court

Lucille and Janet,
I am so sad to learn of Dan’s passing. You are in my thoughts and prayers. He lived a good life filled with joy, adventures, fun and friends. I know you will keep those stories and memories of him in your hearts. Condolences to you and all the O’Leary family members.
Yan Hartkemeyer says
My deepest condolences to Cindi and family. I’m shocked and deeply saddened by the sudden loss of Dan. Like many, Dan is more than a colleague, but a dear friend. I have vivid memories of Dan telling me about his loving family, recent birthday, great trips, and ski patrol. It feels like yesterday when he was so happy moving back to the state he grew up, showing me his property on google map, and an invitation for my husband and I to join them for some outdoor adventures.
Life isn’t measured in time. A fulfilling life is one where we build strong relationships, create meaningful experiences, make a positive impact on others, and leave a lasting legacy. Live like Dan O’Leary!
Nicki & Willie says
Dan was the kind of neighbor everyone hopes for but rarely lucks out with — always there with a helping hand, a warm smile, and, more often than not, a cold beer at the ready. After a long day, you could count on Dan to be out on the porch, ready to swap stories, share a laugh, and make you feel like part of something special.
His cheerful spirit, quick wit, and generous heart were the heart of our neighborhood. Dan wasn’t just a good neighbor — he was a true friend who we enjoyed fun outdoor adventures with. He was someone who showed up when you needed help, who checked in just because, and who made everyday life a little brighter for everyone around him. His presence made our corner of the world a better place, and his absence leaves a hole that can’t be filled.
We will always miss him deeply,
Rest easy, Dan.

RIP Dan
Charlie Beaton says
So many great memories early in my life in Helena with Dan and the O’leary’s. Always a kind and thoughtful person. I exchanged a few messages recently with Dan and sure wish I had the chance to reconnect in person. Prayers to all the O’leary’s and I’m sorry not to celebrate his life with all of you this week. -Charlie and Barbie Beaton

I only with worked with Dan for a short time, he sheparded me through tasks that were not familiar to me and did so with patience, encouragement, and grace. I always looked forward to talking with him and left the conversation feeling comforted and well informed. He was the type of person to think of others first, often saying “this will be something we’ll get into your resume”, “you can put your name on this” or “you nailed it, keep going”. He went out of his way to make others successful and make sure you had a laugh along the way. Dan was a friend and exemplary mentor to young and old. I’ll miss our rapport and the love and care he so effortlessly exuded.
Brian Shuck says
Dan was the kind of friend who showed us the true meaning of care and kindness. He had a heart that knew no limits, always willing to sacrifice his own time to help others. With his endless wit about his Irish heritage and his ever-ready offer to take us out for a beer, he reminded us to laugh, to connect, and to cherish life’s moments. He will be deeply missed, but never forgotten.

I got to know Dan through working at CH2M Hill/Jacobs for almost 13 years. He was a great modeler, calm and humble. We talked about modeling and exchanged ideas through Team meetings frequently. He will be greatly missed.
Raymond F. Rogers says
There are few people in this world who embody charisma, character, an adventurous spirit, and genuine compassion the way Dan did every single day. He had an incredible gift for making you feel like the most important person in the room. Dan cared deeply for his friends, and he was one of the most family-centered people I’ve ever known. He adored his family and lived his faith with quiet strength and conviction.
I always admired Dan’s generosity—his willingness to show up for others, to lend a hand, to simply be there when it mattered most. I was lucky to share some unforgettable adventures with him, and I especially cherished the simple moments—sitting with Dan and Cindy, enjoying a beer and good conversation.
The world lost an extraordinary man, but his spirit lives on in all of us. If we each strive to live a little more like Dan, this world will surely become a kinder, better place.
I miss you, my friend. May you rest in peace.
John Schoonover says
They say only the good die young. Well, Dan was certainly one of the greatest good souls I’ve ever known, and I can’t believe he is gone so young. My condolences to his family. I hadn’t caught up with Dan in a couple years and I regret that. I hope he’s near a river of peace. You will be missed my friend.
Miaomiao Zhang says
I’ve known Dan through work at CH2M/Jacobs for over 20 years. We both lived in Kirkland area before Dan’s family moved to Helena MT. We had a lot of fun time at and outside of work, baby showers, happy hours. etc.. I haven’t talked to him for 10 years since he left Bellevue office and I left Jacobs, until a couple of weeks ago. Although it was just through the computer screen, I can feel that Dan is still the same humorous, joyful and warmhearted Dan. He even remembers my husband’s name and of course the brewery we’ve all been to.
Dan, you will be deeply missed.
Melissa Wu says
Dan was always so generous of his time, quick to make a joke and share a laugh, and include you on the next adventure. I am so grateful for his friendship and mentorship. I remember when I first met him, when I was a newly graduated and completely clueless engineer, touring the office for the first time. He was very welcoming and patient and made me feel immediately at ease. Also, I’m pretty sure he was the only one in the office wearing cowboy boots. I knew then that with coworkers like Dan, that I would love working at CH. Dan was my cubicle neighbor for a few years, which I enjoyed immensely. He was always apologizing to me for being on the phone a lot but I never minded. Yes, by sitting near him I learned a lot from him professionally, but really he was just a lot of fun to be around. I’m honored to have known him and been able to call him a friend. My condolences to his beloved family and many friends.
Jesse Woodward says
So glad to have a couple beers with Dan three weeks ago. He invited me to much more for the year. Every time we talked, or IM’d, he would always ask how my family was doing because of tragedy last year. It was nice and sincere and welcoming.
Tony Shum says
Rest in Peace my Friend and thank you… thank you for be that person that brought everyone in the room together with laughter. Thank you for making the world a better place, one smile (and a beer) at a time. Thank you for sharing your love for the outdoors, for biking (and beer), and specially, your love for making friend and caring for everyone you ever met… with a cold beer.. =) RIP my friend.
Brian Eis says
When Tony Shum sent me the link I was stunned and hoped it was some kind of hoax. Does not seem fair. I echo all the kind words from everyone else. He was one in a million. Rest in Peace Dan. You will be missed.
James Kapla says
Reading all the wonderful comments above recalls many fond memories and experiences shared with Dan. One includes a winter paddle down the Snohomish River here in western Washington. It was a miserably rainy and cold day, but was made warm and lively with fun discourse and adventure with Dan and friend (and colleague) Amy. Buckets of water had to be removed from the canoe to avoid risking a capsize. Yes, there was the obligatory beverage on a gravel bar. And to this day I have never seen so many well-fed eagles roosting in a single tree! Thank you for everything Dan, and love to your family.
Maureen Kloker says
We are so sad to hear of Dan’s passing. He certainly lived a beautiful life full of love and adventure. Cindi and family you are all in our thoughts and prayers.
