Board Certified, ready to help in your time of need


Jonathan Abelson, M.D.


I am committed to providing the best oncologic care to patients in my local community. Aiming to guide you along a pathway forward to recovery, I will strive to help you understand your diagnosis and management options, to answer all your questions, and to work collaboratively with you and the rest of your care team.


I am a Board Certified Radiation Oncologist. I graduated as a Dean’s Scholar from UCLA Medical School, where I was the recipient of the Aesculapian Award for service and leadership. I then completed Radiation Oncology Residency at Stanford University Cancer Center, where I served as Chief Resident.

I am interested in all types of cancer, and I have a particular focus on cancers of the Prostate, Breast, Gastrointestinal System, and Head & Neck. I have extensive experience with Stereotactic Radiosurgery as a certified Gamma Knife clinician for Central Nervous System indications, and with High Dose Rate Brachytherapy for Gynecologic malignancies.

I am a member of the American Society for Therapeutic Radiology and Oncology (ASTRO), the American Society of Clinical Oncology (ASCO), and the American College of Radiation Oncology (ACRO). I have presented my research findings at conferences in the United States and internationally.


My primary practice location is Thousand Oaks, CA.
