Jason Chapman, DO, MD

Consulting Psychiatrist

Dr. Jason Chapman is a board-certified psychiatrist serving the Los Angeles area since 2013. He joined The Canyon team in 2018 where he specializes in addiction, personality and mood disorders, as well as anxiety and post-traumatic stress disorder.

Dr. Chapman settled in Southern California after his service in the United States Marine Corps. He was stationed at Camp Pendleton as an infantryman and deployed to the Persian Gulf before his undergraduate studies in biochemistry at Occidental College in Los Angeles, California. He worked as a clinical trials research associate at the City of Hope National Medical Center before completing his medical degree at the College of Osteopathic Medicine of the Pacific in Pomona, California. He later completed an internship and residency in psychiatry at UCSF Fresno Center for Medical Education and Research in Fresno, California. He also has extensive experience providing psychiatric care to incarcerated individuals.

Dr. Chapman’s interest in the study of addiction psychiatry stems from his childhood experience with his father’s addiction. After experiencing the devastation caused by this condition, and upon treating addiction and co-morbid psychiatric conditions during residency, he knew that he had been preparing all his life for this calling. Dr. Chapman’s easygoing demeanor, along with his empathy and thorough assessments, has made him a favorite among his patients and colleagues. He enjoys traveling with his family and “wind-therapy” on his Harley-Davidson Street Glide.
