Gary graduated from Lakeview High School in Lakeview, Michigan, in 1961, where he was an outstanding athlete, participating in football, basketball, baseball, and track. He had a lifelong passion for music and was a talented piano player. Gary proudly served in the United States Marine Corps and National Guard.
Gary spent much of his professional life in the banking industry. He later owned and operated Gary's Paint Store for many years before eventually retiring from Meijer. Gary's true pride was his family. He led by example, valued integrity, and showed up for his family without hesitation. Gary taught his children and grandchildren the importance of hard work, respect, and doing the right thing. His quiet strength and steady presence shaped the lives of his family.
In his younger years, Gary enjoyed skiing, snowmobiling, and hunting at the deer camp with his sons and friends. He found joy in music, golf, and proudly cheering on the University of Michigan's sports teams. In retirement, he especially loved working on word search puzzles, sitting by Lake Jackson in Sebring, enjoying donuts and coffee with Julie, and watching sports on television.
