Treatment Philosophy
My approach to patient care includes obtaining a careful patient history of the symptoms, obtaining carefully selected tests to evaluate the patient's symptoms, reviewing the results of the tests with the patient and deciding on the appropriate treatment for the symptoms and disorder together.
