if you don't mind driving a little ways, we've been very happy with East Bay Pediatrics in Orinda, they're a couple blocks from the Orinda freeway exit off Hwy. 24. Our almost-8YO twins have been going there since birth - their regular doc is Dr. Sarah Handelsman, who's excellent, and we've been happy with all the other docs that they've seen for assorted sick visits over the past 7+ years
