Growing up he played baseball and soccer, excelling in soccer on various teams until a knee injury ended his competitive pursuits. He played the piano and served his church as an altar server and his community as a scout, attaining the level of Life Scout.

John valued the close friendships of brothers Rudy and Laszio, sharing biking adventures together, as well as trips to Wildwood with co-workers and friends Stephanie and Patty.
