Are there any animal volunteer programs for teens in the Bay Area?

I love animals and I want to volunteer over the summer. I will be 14 in a month. I will be a freshman come next august. I can't volunteer with my mom because she is allergic to fur. I was looking for something local to me. San Mateo County. I know that both the SF and Oakland Zoo's have programs, but that's far to drive for me. Pacifica is fine too. Any ideas are welcome. Thanks!
