Director, Otto J. Ruesch Center for the Cure of Gastrointestinal Cancer
John Marshall, MD, is a global leader in the research and development of drugs for colon cancer and other GI cancers. He is the principal investigator of over 150 clinical trials at both the local and national levels. Dr. Marshall is the associate director for clinical care of the Lombardi Comprehensive Cancer Center and the chief of the Division of Hematology-Oncology at MedStar Georgetown University Hospital.
In 2009, Dr. John Marshall became the founding director of the Otto J. Ruesch Center for the Cure of Gastrointestinal Cancer. Combining expertise in molecular medicine, translational research, and a patient-centered philosophy, the Ruesch Center is dedicated to realizing the dream of individualized curative therapies through research, care and advocacy. Seeing about 60 patients each week, Dr. Marshall specializes in cancers of the GI tract at all stages of the disease.
Dr. Marshall's passion for medicine began at an early age when, at 14, he lost his mother to non-Hodgkin lymphoma and dedicated himself to becoming a doctor and helping find a cure for cancer. A graduate of Duke University and the University of Louisville School of Medicine, he completed his medical training at Georgetown University Hospital and has remained there for over 20 years.
Dr. John Marshall's deep care for his patients and his warm humor help him to develop strong doctor-patient relationships. In 2006, he acquired the additional valuable perspective of being a caregiver for a cancer patient as his wife, Liza, was diagnosed with an aggressive form of breast cancer and underwent nine months of treatment. Dr. Marshall counts the relationships with his patients as one of the most gratifying parts of his job.
Dr. Marshall lives in Arlington, Virginia, with his wife Liza and their two children, Charlie and Emma.
