Welcome to the home page of The Mount Sinai Primary Care Faculty Practice Associates (PC-FPA). Primary care physicians are also known as internists. At the PC-FPA, we deal with all medical problems, no matter how simple or how difficult to treat. We are specifically trained to solve puzzling diagnostic problems of the cardiovascular, digestive, nervous, and reproductive systems. Managing multiple illnesses that may strike at the same time – diabetes and heart disease, for example -- is something we do every day.
