“Very friendly, check-in was very easy since they sent me a link to fill it out before I got there so all of the new patient information was done before arrival. I was seen immediately after arrival and given clear instructions for what to do following the appointment. ”

December 17, 2025Dominic C.Verified patient
I really appreciated the care that went into this appointment. The receptionist was extremely kind and professional, which I feel is pretty rare. Dr. Mamunes listened to me thoughtfully, explained everything very well, and ordered what I felt were the appropriate tests. The tech was relaxed and professional as well. The LabCorp phlebotomist was so kind. Truly everyone was great! I did have to wait about 30 min for my appointment but multiple people apologized and kept me updated on when I would be seen.
November 19, 2025Katie S.Verified patient

The team made me feel welcomed. It did not take long for the doctor to see me. He was professional and very thorough with my examination.
October 12, 2025Phyllis J.Verified patient
Dr Mamunes is phenomenal. The entire staff here was stellar, honestly. From checking in, to scheduling, to having the ability to do my blood work in office because they have a little lab Corp set up.
It's clear that the Gastro Center cares about ease of access and accessibility of the patients. The waiting room was beautiful. Everything is newly updated.
And the attentiveness and care that I received as a new patient was better than any l've received. I cannot recommend Dr Mamunes enough. And that's coming tront a nurse.
August 25, 2025Abigail R.Verified patient
Dr. Mamunes asked me a lot of questions in order to find out what was going on. His explanations were clear, and he showed genuine empathy throughout our conversation. He recommended the right blood tests and the procedure that I needed. The whole experience was smooth and reassuring.

very pleasant, thoughtful doctor

Everyone I talked with at the practice was friendly and helpful. I was there to get help with some moderately embarrassing digestive issues and they made me feel comfortable and listened-to. There were thoughtful touches like a rain sound machine in the exam room to provide white noise while I discussed my problems. Dr. Mamunes was attentive, asked thoughtful questions, and listened carefully to the answers. He was very thorough in answering my questions in turn, and I left the office feeling confident that we will find answers

Everyone was great. Easy and painless.
May 13, 2025Kristen H.Verified patient
Normal doctor that wants to push meds and conduct invasive procedures to solve problems. No options given for dietary adjustments and had to ask for certain tests. Not extremely warm or friendly and wait time was about 45 min once in the room.
