Nadim G. Haddad, MD| Gastroenterology, Pediatric Gastroenterology | MedStar Health
About me
Nadim Haddad, MD, is board certified in internal medicine and gastroenterology. Dr. Haddad serves as physician executive director and regional chief of the Department of Gastroenterology services at MedStar Georgetown University Hospital. Dr. Haddad sees adult patients for conditions affecting the gastrointestinal tract, such as pancreatic and bilary diseases, with a focus on cancer. In addition to adults, Dr. Haddad also attends to pediatric patients for upper gastrointestinal endoscopy.
Dr. Haddad's approach to care focuses on getting to know his patients treating the person, not a disease. His emphasizes hope when patients are facing a serious condition, such a cancer.
Dr. Haddad is also involved in research, focusing in the areas of pancreatic cancer and pancreatic cysts. He was instrumental in developing a pancreatic cyst registry that allows multiple academic medical centers and universities to collaborate and look at the role of molecular profiling.
In addition, Dr. Haddad is active in training the next generation of physicians as an associate professor at Georgetown University. As director of the Gastroenterology Fellowship Program, he was instrumental in it gaining full accreditation.
In his free time, Dr. Haddad is active in the Washington community, involved in his children's schools and with his church.
