Learn about this doctor

Care Philosophy

I have a patient focused approach that begins with detailed discussion regarding symptoms. I am regarded by my peers as an excellent diagnostician, and frequently perform second opinion work. I have been named every year as one of Nashville's top doctors by Nashville Lifestyle magazine and most recently by US News and World Report. I am a leader in the community with regards to education where I coordinate an annual gastroenterology and colorectal surgery course at Saint Thomas hospital. I am well published, including a review article in the New England Journal of Medicine regarding the management of irritable bowel syndrome. I am a leader in new techniques including endoscopic mucosa resection, which can remove flat polyps, tumors and even superficial cancers, preventing the need for invasive surgery. I am the Tennessee leader in endoscopic ultrasound, with the largest experience (over 15,000 procedures), and a referral base throughout Tennessee and surrounding states. Most of all I am a caring person and good listener.Read more

Dr. Mertz Says:

I continue to provide comprehensive gastroenterology care to some of the sickest and most challenging patients in the community and the region.  The people I care for have often already been seen by other gastroenterologists and depend on me to manage or solve more complex problems.

I appreciate any feedback from patients so the patient experience in my practice can be improved.

Wish I could leave 0 stars. This was a horrible experience. Dr. Mertz was condescending and just plain rude. Not to mention I waited 1 hour and 40 minutes after my scheduled appointment time to see Dr. Mertz. He barely said more than 5 words to me...explained nothing, didn't answer my questions..seemed in a hurry to get home for the day. If you want healers for gastrointestinal issues, I left crying and feeling defeated-- like I will never have a solution answer to my problem.

I found Dr. Howard Mertz to be in a hurry, to move on to his next patient or whatever his agenda was. I found him to be very condescending. He failed to explain to me what my test results were. He gave me two prescriptions one of which I researched on the internet and found the drug was used for seizures and neuropathy of which I had neither. He also gave me a prescription for pain pills and sent me on my way. No, I would not recommend this doctor.

Dr. Mertz says...

I have special expertise in inflammatory bowel disease.  I trained with Dr Steph Targan at UCLA, a leading IBD expert and research.

I am a leader in treatment of irritable bowel sydnrome, with extensive publications in this area.

I am a leader in endoscopic techniques, especially endoscopic mucosal resection, where I have performed over 500 resections with excellent results.  Many other gastroenterologists send cases to me with difficult to remove polyps or tumors for this special technique that can prevent surgery.

I am a leader in endoscopic ultrasound (EUS), a technique for diagnosing and staging tumors of the pancreas, esophagus, stomach, and rectum.  I have special training in this technique, and was the first in Tennessee to perform EUS.  My experience is the largest in the state and continues to be a high volume service at Saint Thomas West Hospital.
