After participating in the First Tee program for a few years she became an intern, helping younger golfers discover their own path in the sport. After high school graduation she attended SUNY Cortland and played for their women’s golf team. Upon graduating from college, she returned to the First Tee in New York and became a full-time coach and Girls Golf Coordinator.
