"Dr. Nunez is excellent. He did the upper and lower GI on me and I did not have any discomfort. His follow up visit was extremely informative, he explained clearly and in detail what my issue is and what I need to do about it. Very happy with the doctor. About all the administrative stuff, seems all these doctor's offices are doing the same kind of thing, consolidating doctors and following procedures that leave me a bit cold, especially the phone systems. So, I am not going to say anything particularly good about all the administrative parts of any of these places, but the doctor himself seems excellent to me."

He is willing to listen to any questions I have and never acts like he has to run to the next patient. I have only the utmost of praise for him."
"Two years ago, my primary care physician told me that it was time to have a colonoscopy. Five years previously, I had Dr. Michael Nunez do the same procedure and since I was pleased with his work, I requested him again. This past month, I was told that I needed an upper G.I. Endoscopy. I was pleased to see that was also in Dr. Nunez’s field of expertise. When I informed the scheduling staff that my primary care doctor said that I needed it done as soon as possible, I was able to get an appointment the next day. As with my previous times with Dr. Nunez, I was pleased with all of the information given both before and after the procedure. Instructions were very clear and easy to understand.
