Tony DiLeo served as the 21st head coach of the Philadelphia 76ers of the NBA. He took over the position mid-season on December 13, 2008 after then-head coach Maurice Cheeks was fired after starting the season with a 9-14 record. The team went 32-27 under DiLeo's leadership (finishing the season 41-41 overall), and lost their Eastern Conference quarterfinals series to the Orlando Magic. At the end of the season, DiLeo withdrew his name from consideration to return as head coach, opting instead to return to the Sixers' front office as senior vice president and assistant general manager.
DiLeo was a basketball star at Cinnaminson High School in New Jersey.
DiLeo played basketball at Tennessee Tech and La Salle University, where, as a junior, he was named first-team Academic All-American and went on to graduate maxima cum laude from the La Salle School of Business.
