Nate, I am saddened by the passing of your dad. My kids loved him as a teacher in Clancy, as did I. Also really enjoyed crossing paths an telling stories with him at the wrecking yard. We shared interests and he always went out of his way to help me out. RIP AL.

Mr. Sinerius’ family,
We are heartbroken to see that this lovely man passed away. My girls had him in Clancy for fifth grade, and they were just reminiscing about him last Tuesday at family night. He was so kind and patient with the kids, and such a good sport about all the silly things they did in his class. He was so loved and made a difference in so many lives. It’s sad he had to leave this life too soon! RIP Mr. Sinerius, you will never be forgotten.

Nathan, I am saddened to her of Al’s passing at this time of year. He was fun to play poker with and poke fun at. Wandering around the wrecking yard and listening to his stories was fun. A 10-minute car drop off usually lasted an hour or so. We will all miss him. Don

What a great man..! He taught my brother in 5th grade and a couple years later I was a 5th grader in the opposite class.! He always welcomed me with the friendliest greeting and the warmest smile. For the next 25 years after that, when we’d run across one another it was always jokes and great laughs
Rest In Peace Mr. S.

I remember Allen teaching my kids there in Clancy. I hated to see him retire. I also remember when he started the wrecking yard and how it expanded. It was always a pleasure to visit with Al.
