Treatment Philosophy

I take an evidence based, patient centered approach to your evaluation and treatment. Each consultation will begin with listening to your questions and concerns, and a thorough medical history, physical examination, and review of any available imaging. Together we will decide on the best treatment course within the framework of evidence based gold standard medical care. I treat every patient with the same care and compassion that I would expect for myself and my family.
