After graduating he married his high school sweetheart, Susan. Although they didn't stay married, they raised 3 children, Penny Spoonemore, Becky Muscato, and Joseph DeMent. Bill went on to marry Betty Mastbergen in 1999, and the next year they welcomed another son Jonathan DeMent. Bill and Betty remained married until her passing in 2021.

Over his 74 years of life Bill enjoyed fishing, baseball, watching wrestling, spending time with his children, and of course his beloved dog.
