As a concierge physician with Johns Hopkins Personalized Care and general internist, I am grateful for the opportunity to develop longitudinal relationships with my patients. I believe in meeting my patients where they are, as they are, and listening first. Then, we work together with the shared goal of their best possible health. A healthy lifestyle is the first step; keeping people healthy is my favorite thing to do. I am also constantly updating my medical knowledge so that my patients can benefit from the highest-quality medical advances and approaches. I am adept at coordinating care across multiple specialists when needed, and ensuring that my patients feel supported through their medical journeys. I received my AB in History at Stanford and my MD from Yale.
