Dr. Duman is the best Doctor. He cares very much for his patients. He takes the time to listen to my problems , and tries to help me in any way he can. He gives me the best advice about what to do. I trust him completely to always do the right thing for me. He patiently explained everything so I can understand , and make a decision with his help. One can tell he cares very much about his Patients. When I walk out of his office I feel better., because I know I have a Doctor whom I can trust to do the right thing

Dr. Dumon was very helpful, really seemed to understand where I am with my GI tract. However, his group didn’t contact me to set up the follow up appointment, and then finally I scheduled but he could not see me for FIVE months. Also, still waiting for a call-back to see next steps and necessity for a colonoscopy. So the visit was great, doctor seems great, but follow-up not so great, so for now I’m marking staff and helpfulness as 3s.

I was very confused and concerned about my condition. Dr Duncan reassured me that I’m properly diagnosed and my course of treatment is correct.

Very personable and easy to communicate with. Laughed at my lame jokes, making the colonoscopy that much more fun! :)
Staff is so professional and caring. Doc is too.
