About Me

Brian Ronson, M.D., is a dedicated physician, educator and innovator who is committed to delivering the highest quality care while advancing the field of radiation oncology. 

At City of Hope® Temecula Radiation Oncology, he specializes in the treatment of breast, head and neck, skin, brain, lung and prostate cancers. He also focuses on treating metastatic disease using advanced techniques like stereotactic radiosurgery and stereotactic body radiation therapy (SBRT). 

Dr. Ronson attended Johns Hopkins University as a scholar-athlete, competing in swimming and water polo. He earned his medical degree from the University of Maryland Baltimore before completing a radiation oncology residency at Loma Linda University Medical Center in his native Southern California. While there, Dr. Ronson contributed to research publications and a patent application. 

Since 2005, he has called Temecula home with his family. Patients benefit from his extensive experience in treating many types of cancer, his technical skill, compassionate approach and a highly trained team dedicated to providing optimal care. 

“Dr. Ronson was very thorough with his exam, spent time talking and listening to me. He was very straightforward, but compassionate. He also had a sense of humor. I was confident that I had chosen the right doctor.” – Patient

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.
