I had Dr. Hata in Hickory and that is a Center of Excellence also I know that is in a diff Direction than what you said but thought I would throw it out there for you he is Wonderful!
I had my RYN in Feb. I used http://carolinaweightlosssurgery.com/default. Dr. Roc Bauman. It was a great experience. and yes they are a Center of Excellence. They are in Concord NC.
I had my surgery at Durham Regional through the Duke Weight Loss Center in June from Dr. Aurora Pryor. She's the tops in my book--professional, warm, and excellent surgeon.
