Hi, I live in southern NJ, and my GI Doc is in Philadelphia, at Pennsylvania Hospital.
His name is Dr Fran Dufrayne, very nice, very good doctor, down to earth, you can talk to him, hes not one of those stuffed shirt kind of doctors...
You can also try University of Pennsylvania Hospital, I hear Dr Lichtenstein is awesome, he is a Crohns specialist...I personally havent switched to him, cause I am comfortable with Dr Dufrayne. I'm sure there are docs closer to where you are gonna be moving, but good luck with your search....
