Braves Lacrosse

Meet the Coach

Hired in 2019, Coach Kevin Duffy brings over two decades worth of experience coaching lacrosse at the high school and youth levels. Duffy has turned the Braves into a perennial NorCal powerhouse while compiling a 77-30 record over his tenure. Most notably, in 2024 the program capped off three consecutive undefeated VVAL championship seasons by earning the school's first ever NCS Championship in lacrosse. The team finished with a top 25 overall ranking in the state of California for their success.

The son of a collegiate lacrosse player, Coach played on two championship teams with Cal and played with The Olympic Club for 15 seasons. He is a proud member of the UC Berkeley Lacrosse Hall of Fame.

Besides his playing experience, Coach Duffy coached at University High School (SF), Piedmont High, Napa Force youth lacrosse, and has been an assistant at JS.
