Nashville, TN and Monterey, CA – July 1, 2025 – OneOncology, a physician-led national platform supporting independent oncology practices, and its Monterey-based partner Pacific Cancer Care, today announced they have signed definitive agreements to acquire the radiation oncology clinic located at 15400 National Ave., Suite 100 in Los Gatos from Good Samaritan Hospital. The parties anticipate that Pacific Cancer Care will begin seeing patients at the Los Gatos clinic location beginning in October.

This acquisition ensures continued patient access to the region’s only community-based radiation treatment facility—a critical resource for delivering high-quality, accessible cancer care. The clinic’s linear accelerator provides multiple forms of external beam radiation therapy with precision targeting that spares healthy tissue. These advanced technologies are commonly used to treat cancers of the breast, head and neck, cervix, prostate, brain, lungs, and skin.

Zach Koontz, MD, President and Managing Partner of Pacific Cancer Care, said, “Integrating radiation oncology into our care model strengthens our ability to serve patients across the Central Coast. It means more people can access comprehensive, high-quality cancer treatment closer to home and at a significantly lower cost than hospital-based care. This expansion reduces the burden of travel and fragmented care for our patients and their families.”

With the addition of radiation oncology, Pacific Cancer Care provides a full spectrum of services, including medical oncology, hematology, clinical trials, palliative care, chronic care management, health coaching, in-house laboratory services, and an oral pharmacy.

“We’re proud to support Pacific Cancer Care in expanding services that are essential to their community,” said Jeff Patton, MD, CEO of OneOncology. “This acquisition ensures patients can continue to receive world-class cancer care in a convenient, physician-led setting.” OneOncology and Pacific Cancer Care plan to invest in new technology and infrastructure at the Los Gatos radiation oncology center to further enhance care delivery and patient experience.
