Dr. Brettholz was very professional, knowledgeable and had a very pleasant and easy disposition. He knows his stuff and I would highly recommend him.
I received the same thorough, professional care I receive at each visit, validating Dr. Brettholz’s rating as the best gastroenterologist in New York. I’ve noticed some comments on your comments page about this doctor, about long waits to see him, difficulty with his staff getting back to patients, etc. Welcome to the world of having a popular, highest-rated New York doctor. With someone of Dr. Brettholz’s ratings, you’re going to have long waits to see him because the best doctors are overbooked – if, like him, they won’t turn away patients. He also spends plenty of time with each patient. His assistants do the best they can with their workload.
Scheduling an appointment was easy. The office staff was courteous and professional. I have complete trust in Dr. Brettholtz. I accomplished what I wanted to do. And that makes it a happier day.
He is my third Gastro because my previous two refused to do more than a test or two, diagnose me with IBS, and prescribe meds that made me super drowsy. Dr. Brettholz understood my worries and made me do every test possible to rule out any other causes of my problems and thus, giving me piece of mind. I highly recommend him if anyone is looking for a proactive and friendly doctor.
Great doctor. He definitely knows what he’s talking about. Very experienced and makes you feel very comfortable. Highly recommended!

Staff was incredibly efficient and very friendly. They were ready to see me before I even finished my paperwork. Dr,. Brettholz has such a pleasant and disarming manner. He does not rush the exam and takes time to engage in small talk and pleasantries. I really felt like he was fully engaged and willing to give me all the time I needed to ask any questions. And even though you know he has explained the procedures and preparations thousands of times, I felt as if this was the first time, he was describing what to expect. He is a first-class physician.
