In 13 seasons of Division I play, Brunswick’s hockey program has solidified itself as one of the most competitive high school programs in New England, securing tournament berths in 2010–2011, 2011–2012, 2014–15, when the team won a school-record 26 games; 2015-16, when the Bruins earned their first-ever berth in the Elite 8 Tournament, featuring the top eight teams in New England; and 2016-17, when Brunswick won its first-ever playoff game at the Division I level and advanced to the semifinals of the Large School Tournament.

In 2017-18, the Bruins won three straight playoff games to capture the NEPSAC Large School Tournament championship, the school's first title at the Division I level. 

After missing the playoffs in 2018-2019, Brunswick returned to the Large School Tournament semifinals in 2019-2020, a year that saw the Bruins win 21 games.

No official NEPSAC games or playoffs were held in 2020-2021 due to the COVID-19 pandemic, although the Bruins played 19 exhibition contests. 

Most recently, in 2021-2022, Brunswick won 21 games, including two playoff contests at Hartong Rink, before falling in the Large School Tournament championship to Kent.
