Treatment Philosophy
My philosophy in medicine is taking a partnership-approach to each individual’s health and needs. I don’t like to tell patients what to do, but instead discuss the options, benefits and risks, and come to a decision with the patient. I was trained to treat each patient like you would a beloved family member, and I strive to do so with each visit.
