I prefer someone in a university teaching hospital. I find they tend to keep up with new advancements, collaborate with other Docs more, and are on salary so they don't push for surgery (private practice surgeons get paid by the procedure, so guess what they like to do?!). How about calling the GI dept. at the University of Louisville and asking them for a referral?
I hope you find a great one soon! They are the last thing you ever really want to have -- but life savers and real blessings when you do need them!
