The Oncology Service - Leesburg

TOS is an oncology-exclusive practice specifically dedicated to providing outstanding and compassionate service to our pets with cancer and their caretakers. We do this with expertise in advanced diagnostic techniques and all forms of cancer treatment. Within our team and in collaboration with our primary care and specialty veterinary colleagues, we assist owners of pets with cancer in determining and delivering optimal therapy.

TOS is proud to have assembled one of the largest faculties of innovative veterinary oncology specialists within a single group. Indeed, very few hospitals including university centers approach the collective training, experience, and publication record of our doctors.
