Mayor Michelle Wu has declared Sunday as “Mike Gorman Day” in Boston, according to a city news release on Friday.
Gorman, who has worked as a Celtics play-by-play broadcaster since 1981, is retiring at the end of the season.
“Mike Gorman has made an impact across generations of Celtics fans, families, and visitors throughout his 40-plus years as the voice of the Boston Celtics,” Wu said. “His passion, intellect and ability to make every fan feel special and locked in for the whole game is unmatched.”
Wu will join the Celtics and NBC Sports Boston to celebrate Gorman’s career at his final regular-season game this Sunday at TD Garden. Gorman will be on the local broadcast of the Celtics’ first-round playoff series.
In a halftime presentation, Gorman, the longest-tenured play-by-play voice in Boston professional sports, will be honored with a video tribute, speeches from Celtics ownership, and other special surprises.
“Mike Gorman has made an indelible mark on Celtics fans, and we can’t think of a more fitting way to celebrate his career than at the last home game of one of the most memorable regular seasons in the team’s history,” said Celtics president Rich Gotham.
In addition to calling Celtics games, Gorman served as the primary announcer for ESPN’s Big Monday during the 1980s. He has also called the NCAA basketball tournament on CBS, the NBA playoffs on TNT, and the 2016 Olympics on NBC.
After growing up in Dorchester, Gorman attended Boston State, now known as UMass Boston.
