About Me

F. Marc Stewart, M.D., often says you’ll hear him before you see him — he’s known for whistling as he walks through the halls, a habit he picked up from his grandfather, a small-town physician he admired deeply. As a boy, Dr. Stewart would follow his grandfather on rounds, where he first witnessed the power of empathy, respect and compassionate care. 

“What I witnessed as I tagged along behind my grandfather made medicine an easy career choice for me,” says the hematologist-oncologist at City of Hope® Cancer Center Duarte. “His example has greatly influenced the way I relate to patients, their family members and my colleagues.” 

With over four decades of experience, Dr. Stewart brings deep knowledge and leadership to City of Hope. He previously served as medical director of Seattle Cancer Care Alliance at Fred Hutchinson Cancer Research Center for 20 years and held similar leadership roles at the University of Massachusetts and the University of Virginia. 

Originally from Indiana, he earned his medical degree from Indiana University School of Medicine in Indianapolis, where he also completed his residency and fellowship in oncology. 

Dr. Stewart’s research focuses on engraftment biology (how transplanted blood cells grow and recover), cellular immunotherapy (harnessing the immune system to fight cancer), medication safety and health care delivery. He’s proud to be part of the City of Hope team and is grateful for the opportunity to support patients and families every step of the way. 

"Becoming a part of an organization that conducts outstanding research and advances care for cancer patients is a real privilege."

Patient reviews
The patient ratings and comments on this page are obtained from an external Press Ganey® outpatient survey provided to all eligible City of Hope patients within one to two weeks of their treatment occurrence. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five- star rating. In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, or do not relate to the patient's experience with the doctor involved. As a result, the comments are the views and opinions of the patients surveyed and are not endorsed by, and may not necessarily reflect the opinion of, City of Hope.
