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.Â 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.
