The Levine Group is a group practice staffed by Johns Hopkins Internal Medicine physicians who work together as a team. Each physician typically sees patients one half day per week, and dedicates the remainder of his/her time to teaching and performing cutting edge research in health care. Every patient has a personal physician in charge of his/her medical care. All doctors in the group are available to see each other's patients when necessary for urgent issues. This model allows our physicians to fulfill the Johns Hopkins mission of research, teaching and patient care, while ensuring timely attention to the needs of our patients.
