About Michael Nunez, M.D.

Why did you choose to specialize in Gastroenterology?

I’ve always been interested in science and how technology can help people in their everyday lives. Gastroenterology provides a perfect blend of direct patient care and the use of technology to diagnose and treat complex disorders found in patients with GI conditions.

Do you have a specialty of interest within GI?

Most of what I do as a gastroenterologist on a daily basis involves colon cancer prevention and the treatment of reflux complications and peptic ulcer disease. I also have special training and interest in advanced therapeutic endoscopy techniques, such as ERCP and endoscopic ultrasound, radio frequency ablation and mucosectomy.

Where did you study?

Undergrad: Louisiana State University, Medical School: Duke University, Residency and Fellowship: University of Texas Southwestern.

What certifications do you hold?

I am board certified in Gastroenterology.

What do you and your family enjoy doing in your spare time?

Off road cycling, tennis, cooking and listening to classic jazz.

Do you have any special honors or recognitions in your medical career that you would like to share?

I was a contributing author to Sleisenger and Fordtran’s Textbook of Gastrointestinal and Liver Disease in years past. I have been selected as one of D Magazine’s Best Doctors each year since at least 2000.

Please list your professional affiliations.

Dallas County Medical Society, Texas Medical Association, American Society of Gastrointestinal Endoscopy and American College of Gastroenterology.


Dr. Nuñez is amazing! He is attentive, caring and patient. He took his time investigating my stomach virus a couple years ago. He told me only two people in Texas had that virus. All the medical staff are friendly and professional.

Dr Nunez is wonderful! He’s kind and caring enough to call, personally, to check up after a procedure, and he’s always ready to listen. He has seen me through some trying times and I feel as though he’s as much a friend as a doc.

My experience with Dr. Nunez was great! He is very easy to talk to and explains scenarios in ways that I feel anyone would understand. Overall it was a great experience with him.
