We're in the process of switching to Intown Pediatrics but haven't had an appointment yet. Our baby is due in a couple of weeks, so I'll be able to give some feedback then. What are you looking for in a pediatrician? I have to admit that my "crunchy" qualifications are pretty low--the pedi we are switching from is quite mainstream but I liked her well enough. She (old pedi) never gave me particularly bad advice and was supportive of extended nursing, though she didn't throw me a party for doing it or anything, which is fine with me.
Personally, my main qualifications are that the doctor is laid back and flexible; i.e. we can agree to disagree on certain things. I went to the meet and greet at Intown and Dr. Sells is definitely pro-vax (and pro the recommended schedule) if that's something you're curious about, but she also said she would work with parents who chose to delay or selectively vax. I have read in other places that she has referred parents to the Sears vaccine book as a good source for info on delayed or selective vaxing. Not sure how she feels about not vaxing at all if that is a concern of yours.
I have also heard wonderful things about Dr. Marion Owen in Decatur. She's a family practitioner and from what I have heard practices very holistically, but last I checked she was not accepting new patients. Not sure about the current situation there. I know a few people who really, really love Carole Hermann, a pediatrician in Decatur.
I'll get back to you on Sells in a couple of weeks if you can tell me specific concerns. PM me if necessary.
