Trimm turned professional in 2008 after signing a contract with the New Mexico Scorpions of the Central Hockey League.
Trimm moved to the ECHL for the 2011-12 season and signed for the Cincinnati Cyclones, but he only played two games for the team before re-joining the Bucks.
The Bucks suspended operations on May 1, 2012 and Trimm moved on to the Wichita Thunder where he scored 76 points which included 35 goals.
However, he only made six appearances before leaving four months later to sign for the Braehead Clan in the Elite Ice Hockey League in the United Kingdom and managed 58 points including 42 assists in 45 games.
In 2015, Trimm moved to the Coventry Blaze of the EIHL, but he only managed to net seven goals in 36 games before he departed and made a return to Glasgow to finish the season, and eventually his career, with the Clan.
