Dr Dietz was at Cleveland Clinic and then with University Hospital in Cleveland. When Dr Remzi left cleceland he said if i ever needed a colorectal surgeon he would only recommend Dr Dietz. Well Dietz has now left Cleveland and is at NYU Langone in NYC. Remzi left Langone and went to Northwell. I also had Dr Shen as my GI in cleveland and they have all left me and it sucks as they are all best in their field for jpouches
