Welcome to the Kaiser Permanente Radiation Oncology Program!

The Kaiser Permanente Radiation Oncology Department is academically oriented and dedicated to delivering high quality patient care. The department is the largest in California and one of the largest in the nation. We offer a unique training experience in the clinical and academic Radiation Oncology setting within a fully integrated healthcare system and a managed care organization.


The Kaiser Permanente Los Angeles Medical Center was opened in 1963. Our residency program was officially founded in 1986 under the leadership of the late Dr. Arthur Kagan and Dr. Aroor Rao. The program initially began with a total of three residents and has since increased to a total of eight residents (two per year). Over the course of thirty years, the department has grown rapidly in size from a handful of physicians in one location to twenty-two full-time clinical faculty across three locations.
