Program Director


Stefanie R. Brown, MD, FACP, FAAP

Medical School: University of Cincinnati College of Medicine, Ohio
Residency: Internal Medicine - Pediatrics - Rutgers New Jersey Medical School, Newark, New Jersey 

Dr. Brown was born and raised in New Jersey and returned to her home for residency and her first 7 years of faculty experience. As a Med-Peds physician, she considers herself 100% Internal Medicine and 100% Pediatrics. The variety of her administrative, clinical, educational, mentorship and research responsibilities inspire and motivate her, and she has a true passion for each. Her current research endeavors are based in academic medicine and curriculum development. She feels lucky to work in an institution where she is given freedom to explore and encouraged to pursue innovation in all aspects of her career.

On a personal note, Dr. Brown lives in South Beach, facing the ocean, where the multitude of extracurricular activities available is only out measured by the beauty of her surroundings. In her time off, she belongs to a dinner club that meets every Monday night and on the weekends she enjoys outdoor activities such as biking, lying on the beach and searching for that magical 8th day in the week.
