Williams was a four-sport athlete (football, basketball, baseball, and track) at Plano East Senior High in Plano, Texas. He played two years of football at Austin College before transferring out when he realized that his passion was volleyball, where he went on to have a successful beach career. Primarily playing setter, he had success playing on men's teams that competed at the USAV Open Championships.
Williams' wife, the former Cory Sivertson, also a setter, is the only volleyball player inducted into the Baylor Hall of Fame, ending her career holding 18 Baylor records, many of which still stand today. Williams credits his successes on the volleyball court to Cory's success, knowledge, and influence. Jason and Cory have two children, Callie and Barrett. Entering her sophomore season, Callie plays volleyball for the University of Tennessee.
