The Celtics have extended their head coach’s contract, announcing today in a press release that Joe Mazzulla has officially signed a new multiyear deal with the club.
“We are very excited that Joe has agreed to extend with the Celtics,” president of basketball operations Brad Stevens said in a statement. “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.”
Mazzulla, who joined the Celtics’ coaching staff in 2019 as an assistant, was unexpectedly thrust into the head coaching role ahead of the 2022/23 season when Ime Udoka was suspended by the club. Udoka never returned to the team, resulting in Mazzulla earning the position on a permanent basis.
Mazzulla has acquitted himself very well in his first three years as the Celtics’ head coach, winning 57, 64, and 61 regular season games for an overall record of 182-64 (.740). He has also guided Boston to a 33-17 record in the playoffs, as well as a 2024 championship.
Mazzulla finished third in Coach of the Year voting in his first year on the job in 2022/23, then ranked fourth a year later.
He’ll face a new challenge in his fourth year in the role, as the Celtics have spent the offseason retooling their roster to cut costs after operating above the second tax apron last season. With Jrue Holiday and Kristaps Porzingis no longer on the roster and Jayson Tatum expected to miss most or all of 2025/26 while he recovers from a torn Achilles, Mazzulla will have to find a way to maximize a group that features less talent than his previous rosters.
