I don’t know what planet the folks who gave Dr. Mertz bad reviews are from, but I had a wonderful experience and am so glad to have found him! He is warm; friendly; highly knowledgeable, and thorough. Never did I feel rushed. He listened to my concerns, explained his plan of treatment going forward. He answered all my questions, making sure I understood procedures. His staff is great, especially his nurse, Stephanie. I did not have to wait long, either in the waiting room or the exam room. Front desk personnel were efficient & friendly. After struggling for years, I feel I have finally found someone who understands my Gastro problems and will help me overcome them … he’ll definitely do his best to do so!
