Dr. Oh is a great gastro Doctor and a class act. He takes the time to talk with you and understand your issues. I have been going to Dr. Oh for years now and during every visit he sits and explains to me what is going on with my issues and what needs to be done to help resolve them. He will even draw diagrams on his board in his office to help you understand better If needed. I had my first ever colonoscopy done this week. Hesitant and even a little bit nervous I must say. He explained and made the procedure just as it went. A breeze. The Mountainside Hospital staff was exceptional too. If you are in search of a top notch gastroenterologist. Look no further.
