About

About

I believe that each patient is a complex individual with his/her own unique biopsychosocial components. What this really means is that I care about how you feel, how you want to be treated, how you live, and how life has affected you. I don't just treat your disease; I treat the complete you. Unlike, most modern days physicians, I do spend a reasonable amount of time with my patients and address all of their concerns. But of course, if you are in a hurry and just want me to be quick and simple, I can do that too!
