The terms of the deal were not made available, per the Celtics’ policy.

“This is truly a blessing,” Mazzulla said in a release. “I would not be here without my faith, my wife, and my children. We are thankful for the partnership with our ownership groups, Brad’s mentorship, and the support of our staff. Most importantly, I am grateful for the players I have been able to coach the past three seasons. I look forward to competing for the Celtics and the city of Boston.”

Mazzulla has led the Celtics to a 182-64 regular season record in his three years leading the team. They have made the playoffs every season and won the NBA Finals in 2024.

“We are very excited that Joe has agreed to extend with the Celtics,” Celtics president of basketball operations Brad Stevens said in the release. “He understands the job and has a passion for the Celtics that is only rivaled by our most die-hard fans. He’s worked hard and accomplished amazing things in his first three years as a head coach – including averaging over 60 wins per season and winning the 2024 NBA Championship. Joe is a gifted leader who brings a consistent commitment to learning, improving, and maximizing each day we get to compete for the Boston Celtics.”

The former Mountaineer guard was named an interim head coach on Sept. 22, 2022 after Ime Udoka was suspended for the entire season for violating team policies. Mazzulla was named head coach on Feb. 16, 2023 after leading the Celtics to a 42-17 record at the NBA All-Star Break. The Celtics finished the regular season 57-25 and lost in the Eastern Conference Semifinals.

Mazzulla played at WVU from 2006-2011, averaging 4.8 points, 2.4 rebounds and 2.6 assists per game. He was a part of WVU’s run to the Final Four in 2010, where he averaged 2.7 points per game.
