You can get lists of the schools that sponsor NCAA fencing (or any other NCAA sport) at the NCAA website. Go to the link below and select “Men’s Fencing”, “Women’s Fencing”, or “Mixed Fencing”. Then pick Division I, II, or, III (or just select “All”).

You will find that the only schools in California with NCAA fencing teams are Stanford (DI), UCSD (DII) and Caltech (DIII). UCSD is transitioning to DI. There could be club fencing teams at other schools.
