Radiation Oncology

Harnessing the latest technology to provide the most advanced treatment options for our patients.

As the premier provider of radiation oncology in Santa Barbara County, Ridley-Tree Cancer Center is proud to provide the latest treatments available, including stereotactic radiosurgery (SRS), stereotactic body radiation therapy (SBRT) / stereotactic ablative radiotherapy (SABR)brachytherapy and image-guided radiation therapy. Our radiation oncologists are board certified and have received extensive training from world-renowned institutions.

Ridley-Tree Cancer Center earned accreditation for radiation oncology services from the American Society for Radiation Oncology (ASTRO) Accreditation Program for Excellence (APEx) in 2017. APEx is a national independent, comprehensive radiation oncology accreditation program based on evidence-based standards of radiation oncology practice and patient care, focusing on process of care, the radiation oncology team, safety, quality, management and patient-centered care.

Our radiation oncologists collaborate with medical oncologists, surgical oncologists, primary care physicians, other specialty physicians and members of our supportive care programs to create a coordinated and multidisciplinary approach to cancer care to ensure the best possible outcome. 

“Evaluating our processes in relation to ASTRO’s highest national standards for treatment safety and quality validates our longstanding rich history and tradition of excellence in clinical practice and acknowledges our ability to consistently deliver high-quality patient-centered radiation oncology care in this community for the past 70 years. Our center was the first to garner this accolade in Southern and Central California, ahead of other centers of radiation oncology excellence such as UCLA and City of Hope.”
