Seeking Blue Shield therapist

I'm looking for recommendations for therapists in network with Blue Shield (we have a PPO plan). It's been a struggle to find anyone, especially for in-person therapy -- we live in Oakland near the Berkeley border. At this point it's not important what kind of therapy, just if they listen and are more useful than a self-help book. After other unsuccessful instances of negotiating with the insurance company, we'd prefer to find someone who takes Blue Shield, instead of dealing with a superbill. Thank you all for your advice!
