Speech therapist recommendations in Berkeley area?

Thanks to everyone who responded to my post a few months ago and encouraged me to get my 2 year old son evaluated for a speech delay. I followed up with the Regional Center, and he indeed has a mild speech delay. Since our insurance covers speech therapy, I was told RCEB won't provide services for free, and the evaluator suggested I seek in-network therapists from my insurance. I did...and there were none in the East Bay. I will ask RCEB for referrals, but I'd also like to tap BPN knowledge. Anywhere from Richmond/El Cerrito to South Berkeley would work for us.

Many thanks again!
