Adventist Health St. Helena proudly welcomes new medical director, Ari Umutyan, MD, to the Martin-O’Neil Cancer Center.

A long-time physician in Napa County, Dr. Umutyan is board-certified by the American Board of Internal Medicine and brings more than a decade of cancer-fighting experience to his medical oncology practice. He specializes in comprehensive and compassionate cancer care, of breast and lung cancers, malignant hematologic conditions such as lymphoma and leukemia, as well as non-malignant blood concerns. As medical director, Dr. Umutyan will oversee clinical care at the Martin-O’Neil Cancer Center, focusing on offering world-class care to patients in a setting that allows them to stay close to home.

“Dr. Umutyan is highly respected for his expertise, intellect and dedication to his patients,” says Steven Herber, MD, president of Adventist Health St. Helena. “We are delighted he has chosen to join the excellent medical staff at the Martin-O’Neil Cancer Center and look forward to his leadership as we continue to offer advanced oncology services in the Napa Valley.”

After growing up in different parts of Europe, Dr. Umutyan completed his undergraduate studies at St. Mary’s College in Moraga, Calif. He received his medical degree from the University of Southern California Keck School of Medicine in Los Angeles, Calif. He completed his internal medicine internship and residency at University of California Davis Medical Center in Sacramento, where he also served as an internal medicine chief resident for one year while exploring his passion for teaching. He completed his fellowship in medical oncology and hematology at the University of California Davis Medical Center.

Dr. Umutyan is fluent in English, Armenian, German and Turkish, which has formed the foundation for a unique and culturally-sensitive approach to patient care. He is dedicated to educating patients about their condition in order to inspire greater involvement in their care.

“Hearing a diagnosis of cancer can be overwhelming,” he says. “I’m dedicated to helping my patients understand the specifics of their condition, treatment options and then to be by their side during the journey.”

When Dr. Umutyan is not seeing patients, he enjoys road biking, long-distance running, soccer refereeing, skiing and spending time with family.

Dr. Umutyan is accepting new patients at the Martin-O’Neil Cancer Center at the Adventist Health St. Helena Medical Center at 10 Woodland Rd. in St. Helena. For more information, please call (707) 967-5721.
