I don't know if yu'lve looked into them already, but Society Hill Peds. (13th and Locust)isn't too bad. It's a large practice, all women, all bf'ed their kids. Some of the docs are a little mainstream for my taste, but the last time I was there the doc I saw didn't bat an eyelash at dd still cosleeping at 18 months. I know people who go there who don't vax or only selectively vax, and they say they don't have a problem. The support staff are okay too. I've certainly seen much worse.
