Philosophy of Care

My path to becoming a doctor began with a passion for the power of science and innovation.  As I have progressed throughout my career I have come to find that the most important and fulfilling parts of the job are the personal interactions with patients.   As a non-surgical physician, and as a son of two teachers, I am proud to say that my communication skills are my strongest assets.  I know how essential it is to listen and convey a clear explanation and plan of care for every patient I see.
