Bill SanGiacomo was the head men's golf coach at Trine for 50 years before retiring, but continues to leave his mark on the program as a volunteer assistant.

Under SanGiacomo, the Thunder have never finished lower than fourth in the MIAA since becoming a member of NCAA Division III. During that time, he has coached 33 players to All-MIAA campaigns. Coach SanGiacomo has built a successful golf program since the Thunder were a member of the NAIA, leading his teams to 19 conference titles, 14 state and regional titles, and 14 trips to the national tournament.

He has served as past president of the NAIA Coaches Association, and he coached the United States men’s golf team that participated in the World University Games in France in 1991.

Following the 2011-12 season SanGiacomo retired from his teaching duties on campus that included serving as the director of the golf management program and as the director of the golf academy.
