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.

Why should this matter to you? It means that when your pet comes to TOS, it will be given the highest quality care. It means that for complicated cases or at your request, your pet’s situation will be reviewed by our outstanding team to ensure that the best recommendations are made and that no stone is left unturned as we consider the options for your pet.

Exclusive Focus on Cancer

We don’t do vaccinations. We don’t spay or neuter. We just treat cancer, 4,000 times a year. In fact, our staff’s combined experience totals more than 100 years of oncology practice. During the course of your pet’s treatment, we call on that experience countless times, for a multitude of decisions. This experience could mean the best possible outcome for your pet’s treatment. So if your pet has cancer, and you want the best odds of beating it, you’re looking in the right place. Because we know cancer.

A Team Approach to Cancer Treatment

Often, our patients may have multiple other providers of care including a primary-care veterinarian and/or multiple other specialists. Communicating and effectively coordinating the treatment plan is of paramount importance to us. Your oncologist can effectively be the “quarterback” of your pet’s oncology care, distributing the needed tests or treatments to the most appropriate provider.

Access to Unique Treatment Options

Between the numerous clinical trials we regularly participate in and the state-of-the-art equipment in our facilities, you have access to a number of unique options, resulting in a treatment plan that is specific to your pet.

Clinical Trials

TOS is committed to providing the most advanced diagnostic and treatment options for our patients. Sometimes, this means going a step further and assisting in the development of those options. To that end, TOS is pleased to participate in clinical trials that seek to provide the larger veterinary community with answers and select patients with what may be their only hope for treatment. View Ongoing Studies
