You can try reaching out to the stuttering foundation or national stuttering association and see if they can connect you with someone who knows Cali therapists and can recommend one. If that doesn't work you might just have to trial and error. I'd avoid ones that focus on fluency or tell you it's ok to stutter but actually teach you a bunch of ways to control your stutter. What helped me was finding a therapist who knew how to help with shame, tension, avoidance, effective communication, spontaneity, comfort. I was shown that I could improve those things then fluency didn't matter and focusing on it only made it a bigger part of my life. That I could stutter naturally, comfortably, say everything I want and not have negative feelings about it. Obviously much easier said than done, but taking the time to find the right therapist is invaluable.
