[3] Beecher began ice skating when he was six years old after spending the summer playing roller hockey and immediately made the local travel team.

However, on February 28, 2021, it was revealed that Beecher had undergone shoulder surgery for a lingering injury and would miss the rest of the season.

[9] Beecher impressed in training camp, and earned himself a spot on the NHL roster to start the 2023–24 season for the Bruins.

[10] He would register his first NHL point with an assist on a Brad Marchand goal against the San Jose Sharks.

Incidentally, Bruins rookie defensemen Mason Lohrei, who had played college hockey at Ohio State University, regarded as one of Michigan's rivals, scored his first NHL goal a few minutes after Beecher.
