About the Provider

Dr. Weinberg is an Associate Professor of Medicine and Attending Physician specializing in gastrointestinal medical oncology and sarcoma. Dr. Weinberg is focused on developing new therapies for colorectal and pancreatic cancers by translating research from animal models into early phase clinical trials in humans. He also studies young patients with colorectal cancer and their microbiome in order to understand the dramatic rise in incidence of left-sided colon and rectal cancers in this population.

Dr. Weinberg obtained his undergraduate degree in biomedical science at the University of Pennsylvania in 2007 and his MD at the Keck School of Medicine of the University of Southern California in 2011. He completed his post-graduate medical training at MedStar Georgetown University Hospital with a residency in internal medicine in 2014 and a fellowship in hematology and oncology in 2017 where he served as the Chief Fellow from 2016 to 2017.

Throughout his medical career, Dr. Weinberg has worked exhaustively to make sure that patients are heard and that they receive the highest quality of care. His training as a resident and fellow at Georgetown leads him in the pursuit of cura personalis (“care for the whole person”), and he brings this mindset every day into the clinic and all his work with patients.
