Dr. Eugene Ahn and Dr. Jonathan Abelson lead the qualified and compassionate team of cancer treatment professionals at Simi Valley Radiation Oncology Center. Along with his team of Radiation Therapists, Physicists and Dosimetrists, Dr. Ahn and Dr. Abelson provide expert care for a wide range of cancer types for patients in Simi Valley. The Simi Valley team delivers state-of-the-art technology in a compassionate environment, including 3D Radiation Treatment Planning, Intensity-Modulated Radiation Therapy (IMRT) and Image Guided Radiation Therapy (IGRT).

The Simi Valley Radiation Therapy facility is located on the campus of the Simi Valley Hospital.

The Simi Valley team has recently added both IMRT and IGRT types of treatment to the services offered at this location.  This allows patients in Simi Valley to receive a modern and ultra-precise treatment without traveling extended distances.  Because radiation is typically a daily treatment for several weeks, not having to travel as far for treatment can make a significant difference.  The Simi Valley team is excited about the opportunity to provide cancer patients with these advanced technologies in a compassionate environment close to home.

“We pride ourselves on the compassionate care that the full team delivers throughout the entire treatment process. Our technology allows us to better serve patients and treat a wide variety of cancer types,” said Dr. Ahn.
