Dr. Berger is Associate Professor in the Johns Hopkins Division of General Internal Medicine and Core Faculty at the Johns Hopkins Berman Institute of Bioethics, with joint appointment in the Johns Hopkins Bloomberg School of Public Health. With an active practice in primary care internal medicine at Johns Hopkins, Dr. Berger focuses his clinical, educational, and research work, as well as his widely read publications for the lay public, on the ways in which shared decision making in the doctor-patient encounter might be in conflict with medical evidence and the political, social, and psychological realities of the patient.

Dr. Berger teaches residents in their internal medicine clinic and medical students on the wards at Johns Hopkins Hospital, and is part of a Berman faculty team which teaches bioethics to residents in a number of Johns Hopkins specialty programs. He is also staff physician at the Esperanza Clinic Health Center, a free clinic serving undocumented Spanish-speaking immigrants.

Dr. Berger is the author of two books for the lay public on doctor-patient communication and on patient preference in the context of medical evidence.
