As an underclassman she spent time in a lightweight 4+ that would go on to win gold in the club category at the New York State Championships. She also spent several years sculling. As an upperclassman she competed in a 2x as well as a 1x.
During her time at Duquesne she competed in a freshman 8+ that would finish 4th at Dad Vails and a Varsity 8+ that stroked its way to numerous top finishes and medals. As a senior on the team she stroked the Varsity 8+ in its inaugural trip to the San Diego Crew Classic as well as a third place finish at the Atlantic 10 Championships.
