    Dr. Mentzer saved my life with his brilliance at surgery and followed up consistently. It's now been 9 years since the successful VAT that Dr. Mentzer performed. I have had no chemo, no radiation....years later I am still here with no evidence of recurrence of the cancer he removed! I am forever grateful!

    I've had opportunities to meet Dr. MENTZER for several occasions. Once when my mom had lung cancer, he handled that situation very professionally and straightforward. And later on, when an issue came up with an incidental finding for myself, I felt like I needed to go to see Dr. MENTZER because He seemed very knowledgeable, very caring, and very straightforward with information. So I would highly recommend him for people that really want to know what's going on with their health.
