Dr. O'Neill is very thorough and answers questions in a very professional way. She makes sure you understand and she genuinely cares about her patients' well being. Her staff is also courteous and very knowledgeable.

I would highly recommend Dr. Domanjko. He is everything you want in your Dr. He listens to you. He explains things so you can understand. He spends time with you. He has done 1 procedure and 2 surgery on me. I am a retired RN and I am very fussy who takes care of me.....I think that says it all. You will not regret it if you chose him for your Dr.

Everything went really smooth and it was very organized. It was very nice atmosphere and the nurses made a nervous experience very tolerable. I just found it very organized and would recommend it to anyone who needs a colonoscopy. Everyone seemed extremely capable.

I’ve had 3 experiences with this group. Dr Farid performed my colonoscopy and he did a fine job. My real impression was made by a Physician Assistant named Liesl Hand. I needed an office visit and she was polite and professional and made me feel at ease in an awkward situation. I wouldn’t hesitate to request her if I have a need to return there.

Dr. Teng and his team were great. The intake was very quick and efficient and Dr. Teng was very personable, friendly and relaxed during the pre-procedure meeting. He always asked if I had any questions after he explained each part of the procedure. After the procedure I saw him again as he explained my results. Because of COVID my husband had to stay in the car but Dr. Teng called him after my procedure and answered his questions. I would highly recommend Dr. Teng and Rochester Colon & Rectal. I was a little nervous going into the procedure (although it wasn't my first) because my husband couldn't be with me. But the nurse and Dr. Teng quickly put me at ease.
