Dr. Muhammad Ali and his staff were very polite and patient before and after the procedure. I have been seeing Dr. Ali for several years now and I would recommend him for any gastro issues you have.

Kind doctor, great office staff and smooth procedure. Definitely recommend Dr Ali.

K.S. Google

Colonoscopy. Staff and Dr. Ali were very nice. Like many large “specialists” groups there were too many people waiting and it felt like an assembly line. But, like mentioned above everyone was very nice, no complaints at all.

Dr. Ali is a very caring Doctor, takes time to explain you problems and explains how procedures will take place and the results. Recommend him for anyone needing Gastroenterology care.
