Spanish speaker OBGYN in the Bay Area recommendation

Hi, I am 4-months pregnant of my first child and I am looking for a recommendation of a Spanish speaker OBGYN who takes United Health Care, basically that is not in the Kaiser system. Preferably in the El Cerrito-Berkeley-Oakland area. I've been seeing a Spanish speaker doctor in the Sacramento area but I am afraid I need somebody closer in the Bay Area as a go further in my pregnancy. Thanks a lot.
