The Internal Medicine residency program at Newark Beth Israel Medical Center provides a well-balanced educational experience in a clinically diverse,
quaternary care, community-hospital setting, with a strong university
affiliation. By providing residents exposure to a mix of urban patients

suburban communities, we offer a broad cultural and clinical spectrum.
Residents thus gain both practical and academic training, balancing supervision
and teaching with gradual clinical autonomy. This provides an ideal framework
to educate the medical house officer.
We are proud that our residency program offers the education that tomorrow's
general internist will need in order to provide superior patient care,
and one which will provide a sound foundation for the subspecialist of
At Newark Beth Israel Medical Center, residents receive experience in
all aspects of primary, subspecialty, and critical care medicine, as well
as exposure to clinical research.
