Mark D. Duncan, MD

Dr Duncan is the best. I brought my daughter to him for care also

I used to assess healthcare quality for a living and the first thing you can tell about this provider is that he cares about his clients. He was very knowledgeable and made sure he explained everything to you In detail and In a way that Is understandable. I'm sure no client will ever be able to say they didn't understand a procedure and the risks and benefits prior to signing a consent form with this provider.

Dr. Duncan is an angel. He is talented and brilliant. Dr. Duncan literally saved my life.
