Coach Joe Mazzulla has signed a multiyear contract extension with the Celtics, according to a team announcement on Friday. Terms of the deal were not disclosed.
“This is truly a blessing,” Mazzulla said in a statement. “I would not be here without my faith, my wife, and my children. We are thankful for the partnership with our ownership groups, [Brad Stevens’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.”
Mazzulla is entering his seventh season with the Celtics organization, having spent three seasons as an assistant and one as the coach of the NBA G League’s Maine Red Claws (now the Maine Celtics).
“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.
Mazzulla is 182-64 in the regular season and 33-17 in the playoffs across his three seasons at the helm. He led the team to the 2023-24 NBA championship with a 16-3 postseason record (.842), the second-highest playoff winning percentage in the NBA since the first round expanded to a best-of-seven series in 2002-03.
“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,” Stevens said.
The Celtics are in the midst of a summer of unrest. Superstar Jayson Tatum tore his Achilles’ tendon during the Eastern Conference semifinals and will likely miss a large portion of the upcoming season. They traded Kristaps Porzingis and Jrue Holiday, then let Luke Kornet walk in free agency to get under the NBA’s second apron and avoid a $500 million luxury-tax bill.
