Jeff Greenwald, MD, is a native of the suburbs of Chicago, IL, and subsequently graduated from Washington University in St. Louis. Thereafter, he completed medical training at Harvard Medical School before returning to St. Louis to complete Internal Medicine residency at Barnes Hospital. After completing this training, Dr. Greenwald moved to Oxford, England, where he practiced as a Specialist Registrar at the John Radcliffe Hospital, spending time in both inpatient medicine and intensive care medicine.

After almost a year overseas, Dr. Greenwald returned to the US and became the first hospitalist at Boston Medical Center, the hospital affiliated with Boston University School of Medicine. There he stayed for a decade becoming their first director of the Hospital Medicine Unit. His work there heavily focused on medical education (for which he won an number of teaching awards) and quality improvement, working on projects to improve influenza vaccination, medication reconciliation, ACS care, pain management and VTE prophylaxis. His work in HIV testing there resulted in Dr. Greenwald's being requested to offer advice to the US Centers for Disease Control and Prevention on their inpatient HIV testing recommendations. He also helped to develop and implement Project RED (a randomized trial of a care transition intervention), and Project BOOST (a national quality improvement project to improve care transitions across the US). He has also had the opportunity to run an AHRQ funded conference on medication reconciliation, advise UHC, and contribute to the NQF?s metric on all cause readmissions, subsequently adopted by CMS.

In 2009, Dr. Greenwald moved to the Massachusetts General Hospital to join the Inpatient Clinician Educator Service as a teaching hospitalist. He is an Associate Professor of Medicine at Harvard Medical School and served as the lead physician for Partners Healthcare's High Performance Medicine Team on Readmissions until 2014.
