He also enjoyed reading, spending time with family, watching UW Wisconsin sports (especially men’s basketball), watching the Green Bay Packers, and listening to the Milwaukee Brewer games on the radio.

Bill had a legacy of helping others, strong devotion to his family, and had a great passion for anything he took on.
