STEPHEN L. IONNA, MD REVIEWS

Everyone in the office was super nice and made a point to make me feel comfortable. They completely explained everything to me as they went along to put me at ease. Dr. Iona was very personable and introduced himself to me before the procedure and asked if I had any questions. He also visited me after the procedure and gave me the results in person. Great experience and a great group of professionals.

For the past 12 years, Dr. Ionna has done the procedures for my wife, brother and myself. Excellant Doctor! Visited me during prep to go through the procedure and once awake, cameback to go over any findings. Always made me feel comfortable. Highly recommend Dr. Ionna.

Dr Ionna is top notch. I have seen him several times in the last 10 years. A true professional. Always at the top of his game. One of best his profession offers. Highest regards.

MARVIN J. LOPEZ, MD REVIEWS

Dr. Lopez was great! He made me feel at ease. He did not rush into my room and rush out. He took his time and explained the procedure to me, asked if I had questions and then after recovery he came back in and we went over the findings. I would recommend Dr. Lopez to anyone and everyone.

Hanna Kremer, P.A. and Dr. Lopez were very thorough and diagnosed my situation quickly and well. Kind, professional and great follow-up. The office staff were also friendly and efficient. I definitely trust Kremer and Lopez and recommend them.

Dr. Lopez is very caring and nice. He talks with you before and after the procedure and listens to any concerns. The staff is very professional and caring as well.

SAID I. NABHAN, MD REVIEWS

Odd to say this but the entire experience was the best prep and colonoscopy I have ever had , and I’ve had many. Kudos to Dr Nabhan and his team.

Dr.Nabham was awesome !!!!!! Made me feel very comfortable and at ease and at ease! Even came in early for the scheduled appointment.

Dr. Nabhan is truly outstanding. My mother was diagnosed with non-genetic stage IV colon cancer. Since we lived a similar lifestyle, I decided to go in early at age 35 for a screening, feeling like a hypochondriac. He reassured me that I wasn’t being over-cautious and was doing the right thing, even sharing a personal story to put me at ease. He promptly scheduled my screening and actually found a polyp that, if I had waited another 10 years for the recommended age, would have likely been more serious. If you're looking for an excellent GI doctor whom you can trust, look no further.
