Though he scored just 3 points in 30 games, he was helping the team prepare for another run in the postseason when the season was ended abruptly.
With his career seemingly at a crossroads, Cassaro used the new NCAA transfer rules to move on to RIT and join the Tigers the following season.
The pairing he made with Aiden Hansen-Bukata proved to be one of the most potent duos in the country and helped RIT win its first regular season Atlantic Hockey title in over a decade.
His abilities on both sides of the puck helped RIT repeat as regular season champions, and this time the Tigers ran through the conference tournament and won all five games by at least 3 goals to capture their first Atlantic Hockey championship since 2016.
As an undrafted free agent, Cassaro turned professional for the 2024–25 season in signing a one-year AHL contract with the Lehigh Valley Phantoms, affiliate to the Philadelphia Flyers, on August 20, 2024.
