My experience with Dr. Oh has been wonderful. Dr. Oh is very professional and knowledgeable. He is very patient in explaining all the concerns and questions I had. He is very thorough and his assistant calls to make sure everything is alright after my procedure.

My visit with Dr. Oh was seamless in its' scheduling and coordination of care I received from office personnel. Dr. Oh is very easy to speak to and he understands that I am interested in my own health. So, once the doctor listened carefully, he prescribed a course of treatment to include a colonoscopy. Since I have experienced problems in the past with the removal of a sizeable polyp and periods of constipation which included an episode of bowel impact, the colonoscopy at this point was a good idea. I told the doctor that I really wanted to know what was causing me to have constipation. Since I am a major fan of large doses of fruits & vegetables, a surgeon at Hackensack University Medical Center in Hackensack stated that I was eating too much of these. I drink at least 2 gallons of water daily along with other liquids and eat sufficient (albeit possibly too much) fiber, it is a puzzle that needs to be solved. Hopefully, the Colonoscopy will disclose why I am having problems.

I saw Dr Oh several years ago and then again last week. He is an outstanding doctor. He spends time with his patients and really listens. He is very kind, caring, and reassuring. I wouldn’t want to go to anyone else.

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.

I saw Dr. Oh today for the first time today. He was GREAT. He took the time to explain everything as well as listen to my concerns. I had been putting off getting another colonoscopy and endoscopy because in the past I didn't have a doctor that made me feel at ease enough to schedule it. Dr. Oh is extremely knowledgeable and I have full confidence in him now. You could tell after one visit how smart he is. He has patience and a great bedside manner as well. I thought his office staff was very nice and helpful.

Very competent, nice, effective doctor.

I have been going to Dr. OH for over 10 years for my colonoscopies and endoscopies. Not only is Dr. OH highly skilled in his profession, but also has a great personality, answers all of my questions and has a great "bedside manner". My wife and a number of my friends also go to Dr. OH. Once, my procedure was held up due to Dr. OH having to attend to an emergency. He is the only doctor that has even apologized for being late. He also has a great office staff, led by Patti.

Dr. Oh was very informative. He explained everything to me in detail using terms the average person can understand. I just met with him last week and I left the consultation thinking that I wished every doctor took the time to explain things the way he did. I strongly recommend him to anyone in need of a Gastro Doctor.

My 7/9/2020 my first appointment with Dr. Oh was a pleasant experience starting with reception and medical assistant. I love it when your appointment with a dr.

Follow up visit after endoscopy and colonoscopy
— Colin Lankshear
What an marvellously kind and expert specialist Dr. Oh is. He goes to extraordinary lengths to explain exactly what's going on in your body and what his treatment plan is so that you know exactly what's going on, going to be done, and why. I will forever be grateful to just how focussed and caring Dr Oh was when I really needed urgent specialist attention. And his staff are all beyond wonderful--kind, compassionate, and on the ball. Go and see Dr. Oh and his support staff for all your tummy troubles--you'll be in exceptional hands!
— Michele Knobel
Support staff must have changed in the past year because the current staff are fabulous. Caring, efficient, friendly, could not possibly have been warmer or more accommodating. Dr Oh himself is impeccably professional, has a wonderful patient rapport, and inspires absolute confidence. I have further appointments in the pipe and will update this review subsequently,
— Colin Lankshear

Dr. Oh is an excellent Doctor , but his office staff would cause me to not recommend this doctor. They are not friendly or helpful or understanding at all. I just called and have called before for biopsy results and was told a week ago and now today he will call me when back from vacation and they did not know when that would be! Are you serious??!! I am very upset and mad!! Then she hung up on me!! Not good service at all and I worked in a surgeons office for 16 years and am an RN.Staff rude!!!
— Kathleen Yannetelli
Dr Oh is fantastic but the woman at front desk (Linda) is rude, inconsiderate and lazy. She has absolutely no professionalism and should NEVER be allowed to answer the phones. Linda turns the answering service on before the office closes and will attempt to to have patients do her job (deal with insurance pre-certification). Dr Oh should not have Linda representing his practice in any capacity. Linda WILL make a normal Dr's visit a horrific experience.
