About Me

George Hajjar, M.D., FACP, always dreamed of becoming a doctor. That dream became even more personal when his mother was diagnosed with breast cancer. Watching her journey inspired him to specialize in medical oncology and taught him the power of compassion in medicine. For Dr. Hajjar, City of Hope® is “the place where I belong.” 

He earned his medical degree from Aleppo University in Syria and completed his training at Seton Hall University in New Jersey. Before joining City of Hope, Dr. Hajjar cared for patients in Porterville, California, for more than 10 years at the Sierra View Cancer Treatment Center. 

Today, Dr. Hajjar serves as the regional medical director for City of Hope locations in the San Fernando Valley, Santa Clarita Valley and Ventura County. He sees patients with hematology and general medical oncology needs at the Santa Clarita clinic.

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.
