He is responsible for assisting head coach Jamie Lockard with all aspects of the program with an emphasis on coaching the goalies and providing assistance with the defense.

Duffie comes to the institution after a standout playing career at Ursinus and more recently leading the program to some of its best seasons in program history during a five-year tenure as an assistant coach and defensive coordinator with the Bears. He most notably oversaw the training and development of two All-Americans defensively and the best season in program history in 2015, as the team punched its ticket to the NCAA Tournament for the first time ever and advanced to the second round. The defense ranked among the best in the country for yielding just 6.5 goals per game, while USILA All-America goalie Brian Neff ranked fifth in the nation with a .637 save percentage and ninth with a 6.41 goals against average during the record-breaking campaign.

Prior to coaching, Duffie excelled as a defender for Ursinus. He capped off his four-year career by being selected to the 2011 All-Centennial Conference First Team as a senior captain after scooping up 35 ground balls and causing 17 turnovers. Ursinus also notched two straight winning campaigns with Duffie in a starting role on defense and advanced to the Centennial Conference Tournament.

Duffie, who also served in admissions roles for five years at Ursinus, earned his bachelor’s degree in business and economics with a minor in coaching from the institution in 2011. He is also the Associate Director of Admissions for Archmere Academy in Claymont, Del. and resides in Media, Pa.
