An NCI-designated Comprehensive Cancer Center

Ari Katerelos, M.D., worked as a nurse and a soldier before pursuing his medical degree and specializing in radiation oncology, drawn to the leading-edge technology and treatments being developed in the field.  
“I was planning to become a medical oncologist when I was studying at UCLA,” he said. “But when I discovered radiation oncology, I knew that was what I wanted to do. It requires very diverse skills and employs a lot of advanced technology. I found that very exciting and interesting.”
Today, Katerelos works out of City of Hope's radiation oncology clinical network location in San Bernardino, California, an advanced facility that provides a wide range of specialized, leading-edge cancer care treatments for Inland Empire residents, including low-dose rate brachytherapy (seed implants) and accelerated partial breast irradiation. 
Katerelos’ San Bernardino facility is one of nine radiation oncology centers recently opened by City of Hope. The new centers expand City of Hope’s reach to outlying communities including Riverside, West Hills and Wildomar.
“Before merging with City of Hope, a lot of patients had to drive long distances, as far as Temecula, to get certain advanced, specialized treatments,” Katerelos said. “Now they can get them from City of Hope, right here in San Bernardino.”
Katerelos enlisted in the Army Reserve after high school. It was a turning point that helped lay the foundation for an outstanding career in medicine, leading to his current position as radiation oncologist at City of Hope’s San Bernardino location. Not only did the Army pay for his nursing training, it also helped Katerelos develop a disciplined mindset and strong leadership qualities.
“In the Army you do anything you’re asked,” said Katerelos, an assistant clinical professor for City of Hope’s Department of Radiation Oncology. “That’s the mindset. You deal with the given situation no matter what the circumstances, and that’s how I look at my role with City of Hope. You find a way no matter what the challenges might be.”
