He grew up in Gilson, Illinois, a graduate of Knoxville High School in 1982. He proudly served 8 years in the Army National Guard, having spent time in Honduras.
Aaron went on to work for Bucky Poynor’s Carpentry. Though the majority of his life was spent being “The Glass Man” while working for both Weather Wise Windows and Vinyl Storm Systems, and later co-owning Knox Glass. After leaving the window business, he worked at HyVee and Dick Blick in Galesburg.
Aaron enjoyed playing guitar, mushrooming, camping, playing cards, watching the history channel and cooking, especially his famous meatloaf. Most of all, he loved spending time with Stacy and being Papa to his grandchildren.
