George Fisher, MD, PhD received his MD and PhD in Cancer Biology from Stanford Medical School where he is now the Colleen G. Haas Professor of Medicine in the Division of Oncology. His research and clinical focus is on gastrointestinal cancers and he conducts numerous clinical trials of novel therapies for patients with GI malignancies.

Dr Fisher has been an American Cancer Society volunteer for over 30 years and a past president of the California Division of ACS.
Dr. Fisher is currently on American Cancer Society Bay Area Board of Directors.

Christopher T Chen, MD is a board-certified, fellowship-trained specialist in oncology and hematology. He is also an Assistant Professor in the Division of Oncology in the Department of Medicine at Stanford University School of Medicine.

Dr. Chen delivers comprehensive, compassionate care for patients in need of early drug development clinical trials and patients with gastrointestinal cancers. As a researcher, he leads the early drug development group and studies how tumor heterogeneity limits the clinical benefit of anticancer therapies in order to accelerate development of novel therapeutic strategies. Dr. Chen’s work has appeared in the New England Journal of Medicine, JAMA, Journal of Clinical Oncology, Science Advances, Journal of Oncology Practice, and Health Services Research.

Dr. Chen attended Harvard College, where he graduated summa cum laude and Phi Beta Kappa in molecular biology. He went to medical school at Washington University in St. Louis on a full-tuition merit scholarship, graduating with Alpha Omega Alpha honors, and did his residency training in internal medicine at Massachusetts General Hospital and hematology/oncology fellowship in the combined Harvard Dana-Farber Cancer Institute/Massachusetts General Hospital program. As a fellow, he received the NIH T-32 Ruth L. Kirchstein-National Service Research Award in Cancer Biology for his work exploring the molecular structure of metastatic solid tumors.

Dr. Chen is a member of the American Society of Clinical Oncology, European Society for Medical Oncology, and American Association for Cancer Research.
