With one year of junior eligibility left, Trivigno signed on with the Massachusetts Minutemen Division 1 NCAA program, joining several of his Waterloo teammates in the elite college ranks.
UMass won the Hockey East regular season title, but was stymied in the conference semifinals.
Trivigno could only watch as his team failed to score a single goal and finished as the national runner-up.
When the 2020–21 season began, Trivigno took the leading role with the team's offense, and serves as an assistant captain.
He led the Minutemen in scoring by a fair margin and easily surpassed his career high despite playing in 10 fewer games.
In the team's quarterfinal match, he led the way with a three-point night as UMass defeated Northeastern 4–1 and then repeated the performance in the semifinal, scoring the game-winner over Providence.
When the Minutemen unexpectedly lost four players to COVID-19 protocols before the National Semifinal (including their starting goaltender), Trivigno provided a spark for, keeping UMass in the game.
He assisted on both the tying and winning goal, passing the puck to an open Garrett Wait (a former Waterloo teammate) in overtime to lead UMass to the title game.
On April 1, 2022, following the completion of his collegiate career, Trivigno signed as an undrafted free agent to a two-year, entry-level contract with the New York Rangers and was assigned to the Hartford Wolf Pack for the end of the 2021-22 season.
