Tammany Veterinary Hospital has been serving the Bitterroot Valley since 2002, treating the horses, cattle, and small ruminants of Western Montana. Tammany Veterinary Hospital is located in Corvallis, Montana, the heart of the Bitterroot Valley.

Tammany Veterinary Hospital is an all service facility treating the whole animal. We have an ultrasound, digital radiology, an in-house lab, and spacious treatment rooms as well as a barn and outside stalls. We use computerized records to have your animal’s medical history at our fingertips and can quickly send radiographs digitally to you, your farrier, or for a consult with another veterinarian.

We take appointments Monday through Friday from 8:00 to 5:00. The veterinarians of Tammany Veterinary Hospital are always available for emergencies. Our staff is courteous and cares deeply about our patients and you the owner. Our veterinary support staff will do whatever they can to make your appointment as pleasant as possible.

Our veterinarians are happy to provide further education for the Bitterroot Valley and to speak at any of your local meetings on the topic of your choice. Please contact the office to schedule a presentation for your group.

We moved into a new hospital in 2016 to better serve our clients, patients, and employees. Just drive up to our convenient drive-up window on the south side of the hospital to check-in. Park and unload behind the hospital. We have an automatic gate on the north side of the hospital to exit. You don’t have to turn around or back your trailer up! We have a spacious lobby for the unlikely event you have to wait or if you want to relax while we take care of your animal.

Or, if you prefer, we can come to your farm with one of our fully stocked trucks.

Please call our office at (406) 961-1321 from 8:00 to 5:00 Monday through Friday to schedule an appointment, get more information regarding our services, and see how we can assist you.

If you reach our office after hours and have an emergency, please call (406) 961-4306

COVID-19 Response


If you have any symptoms of illness, we continue to ask that you reschedule and stay home.
However, due to the improving situation around COVID-19, both our lobby and drive-up window are now open. It would be greatly appreciated if medicine orders and refills could be called in ahead of time so they can be ready for owners when they arrive at our hospital. 

Spring and summer are commonly the busiest time in the equine world. For elective and routine appointments we ask that you plan ahead and schedule accordingly. We will always accept emergencies; however same day and same week elective appointments are not always available this time of year.
