It was my dream since childhood to become a doctor.”

George Hajjar, M.D., says watching his mother face the challenges of breast cancer inspired him to pursue training in medical oncology and instilled the importance of compassionate care. This makes him an ideal fit for City of Hope, which he calls, “the place where I belong.”

Dr. Hajjar received his medical degree from Aleppo University in Syria and continued his training at Seton Hall University in New Jersey. Before joining City of Hope, he spent a decade serving the community of Porterville, California, at the Sierra View Cancer Treatment Center.

Dr. Hajjar is regional medical director for Antelope Valley and San Fernando Valley. He also handles all general medical oncology at Antelope Valley, Mission Hills and Santa Clarita clinical network locations, with a special interest in gastrointestinal cancer. His research in the field has earned him awards from the American Cancer Society and the Cancer Institute of New Jersey.
