He was previously an assistant coach with the Atlanta Hawks and the Milwaukee Bucks of the NBA. A former center at Cal State Northridge and the University of Portland, Sullivan has primarily served as a shooting coach during his NBA coaching career.[1]
Sullivan retired from playing basketball and joined his alma mater Portland as their director of basketball technology before becoming an assistant coach at Lewis & Clark College, during which he was also an office manager at a construction firm in Vancouver, Washington.[2]
Sullivan joined the San Antonio Spurs front office in 2012 as a video intern on the recommendation of then-Spurs assistant Ime Udoka. With the Spurs, he worked his way to a position in player development, where he was tasked with everything from scouting reports to analytics, as well as one-on-one workouts with players. He also worked under Spurs assistant Chip Engelland, considered to be one of the top shooting coaches in the NBA.[1]
Sullivan was named an assistant coach on former Spurs assistant Mike Budenholzer's coaching staff for the Atlanta Hawks on August 20, 2014.[3]
Sullivan was one of a number of assistants who joined Budenholzer when the latter was hired as head coach of the Milwaukee Bucks before the 2018–19 NBA season.[4] [5] While in Milwaukee, Sullivan has worked with NBA Most Valuable Player Giannis Antetokounmpo in developing his shooting ability, which has been considered as the main weakness in the Bucks star's basketball game.[2] Sullivan won his first NBA championship when the Bucks defeated the Phoenix Suns four games to two in the 2021 NBA Finals.[6]
