Jon was the only child of William and Eileen Hackenyos. During medical school Jon married his best friend and biggest supporter, Linda Crook. Together, Jon and Linda brought 3 incredible children into this world. A devoted husband and father, Jon was very active in his children’s lives, especially with his sons’ Boy Scout troop, where Jon served as a merit badge counselor, troop committee chair, and outdoor/activities chair. Jon proudly watched as both his sons earned the rank of Eagle Scout. He was beyond proud of his daughter and sons and how they’ve grown into exceptional human beings.
