Celtics’ Joe Mazzulla Accomplishes Impressive Feat For Fourth Straight Season

Mazzulla last accomplished the feat in March 2025

Boston Celtics superstar Jaylen Brown was snubbed for December’s Eastern Conference Player of the Month award, but head coach Joe Mazzulla picked up the slack.

Mazzulla was named the Eastern Conference Coach of the Month for December on Friday.

“The NBA Coaches of the Month for December! West: Mitch Johnson (Spurs) East: Joe Mazzulla (Celtics),” the NBA’s official account posted on Bluesky.

The 37-year-old Mazzulla has guided Boston to a 21-12 start thus far, exceeding expectations.

He’s seen Brown put up career numbers in another All-Star caliber campaign, while getting the most out of unsung players like starting center Neemias Queta and rookie first-round pick Hugo Gonzalez.

Mazzulla has now earned at least one Eastern Conference Coach of the Month award in each of his first four seasons at the helm.

The Celtics leader won the hardware during his first full month on the job in November 2022 and did it twice during the Celtics’ title-winning 2023-24 campaign (December and March).

Mazzulla was also the Eastern Conference Coach of the Month in March 2025.
