For folks at Cleveland Clinic, I highly recommend Benjamin Cohen. I have seen him for my pouch (and chronic pouchitis, frequent obstructions, the works) for about a decade now at Mount Sinai in NYC, but he very recently left there for Cleveland Clinic (possibly hasn't even started yet, with COVID-19 delaying pretty much everything in life). But once he is seeing patients, I strongly urge you to give him a shot. I found him to be excellent -it took me over a decade to find a gastroenterologist in NYC that really specialized in and understands pouches. I will miss him a lot.
