The Oncology Service

What The Oncology Service does

The Oncology Service (TOS) is a private veterinary oncology specialty practice operating three locations across Virginia — Leesburg, Richmond, and Springfield — providing medical oncology, radiation oncology, diagnostic imaging, stereotactic radiation therapy (SRT/SRS/SBRT), outpatient imaging, and electrochemotherapy for dogs and cats with cancer. The practice is staffed by board-certified veterinary medical and radiation oncologists, including Dr. Rick Chetney, Jr., one of fewer than 100 board-certified veterinary radiation oncologists worldwide, alongside VTS (Oncology) credentialed technicians and Fear-Free certified support staff. Clinical research is integrated into the practice via partnerships with Animal Clinical Investigation (clinical trials) and Ethos Discovery (translational research), with Dr. Heather Wilson-Robles serving as Vice President of Research at Ethos Discovery.

The business operates on a fee-for-service professional services model, with revenue generated from consultations, chemotherapy protocols, radiation treatment courses, and diagnostic imaging procedures. Patient acquisition is driven by a referral-based go-to-market motion anchored in the rVetLink Portal, electronic and PDF referral forms, and Lunch and Learn continuing education for general practitioners, supplemented by direct-to-consumer content marketing (blog, social media) and community engagement through the Pet Cancer Support Group, Pet Loss Support Group, and the annual FETCH Fest pet wellness festival co-hosted with FETCH a Cure. TOS is an affiliate of United Veterinary Care, a strategic operating parent, and one of its Springfield locations is physically embedded within the Regional Veterinary Referral Center (RVRC).

The service surface extends beyond core clinical offerings to include specialized canine and feline oncology nutrition programs, investigational treatment access through active clinical trials, and grief and support resources, creating a comprehensive patient and family experience model. Headcount is reported at 51–100 across the three locations, and no external funding rounds, revenue figures, or public listing status have been disclosed.
