I picked my last doc because I wanted a NCB/VBAC friendly doc. There were like 3 in our city at the time, and a friend had used one doc for her VBAC. He was great, but I only saw him until 31weeks or so.
He moved and transferred me to a very not NCB/VBAC friendly doc. I read local ICAN forums, and got a recommendation from a doula on the site for my current doc, who is my favorite of the 5 OBGYNs I've seen over the last 10+ years. <3 him!
I'd see if there is a natural mommy group in your area, or get in touch with some doulas to get an idea of who is truly supportive once you are in the hospital/birth center/etc.

Trusting God brings life. Believing brings rest.
