Care Philosophy

This content was provided by Dr. Mertz "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."

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.

Dr. Mertz is a thorough, kind and caring doctor. He always takes the time to answer our questions and never makes us feel rushed. His office staff is great too, Stephanie is always kinds and helpful and always called us back in a timely manner..

My husband passed of pancreatic cancer. Originally diagnosed with small pseudocyst in tip of pancreas and told it was no big deal. After getting paperwork from hospital saying possible adenocarcinoma, we asked for CT as Mayo Clinic said scan every month for growth and to remove if growing. It had grown slightly, but assured it was just a different angle. Next months CT had been canceled when we arrived. Two more scans showed growth. Surgery revealed cancer and given 3 mos to live! Devastated.

Mertz misdiagnosed my daughter. He told her she was just constipated and should take laxatives and an enema. The next day, we took her to the ER because she was in such pain. After a scan, a colon blockage was found. Mertz was so certain the blockage was Crohn's disease and placed a stent into the mass. The stent perforated her colon. The mass was NOT Crohn's but was CANCER! The perforation caused her to become septic, almost die, and cancer cells released into her abdomen! DO NOT GO TO MERTZ!!!

I just arrived home after having my second procedure with Dr. Mertz. Dr. Mertz was recommended by my primary care provider so I switched to Mertz about 4 1/2 years ago. I did research on Mertz before I went the first time, and he is literally one of the best in his field. I had no problem getting additional information after the first procedure and had my second with him this morning. Following my procedure, he met with my wife and I and took the time to explain his findings.

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.
