Great doctor. He really cares about his patients health. I was seeing him for some very bad acid reflux and I was taking a lot of medicine to control the acid reflux. He recommended surgery and I have not had any problems since my surgery. I do not need to take any medication either. I also saw him for bad/constant stomach pain and he immediately scheduled a colonoscopy and he found pre cancerous polyps. He referred me to a surgeon and my appendix and a small part of my colon was removed. Thanks to for caring about me and giving me options to take care of my heath. I am so blessed to have him as my doctor.
