Getting Started

Does My Pet Need a Referral?
Yes, our patients are referred by their primary care vet when their conditions indicate a need for specialized expertise in advanced surgery and oncology. When you contact us, we’ll review your pet’s health record and schedule an initial consultation to evaluate your pet’s needs.
Do I Need a Board-Certified Veterinarian?
If your pet requires specialized care outside the scope of your primary vet, you may need a board-certified veterinarian. Our board-certified vets have completed 3-4 years of additional training beyond veterinary school in specific areas of surgery and oncology.
What to Expect in the First Appointment?
During your initial appointment, one of our board-certified veterinarians will review your pet's history, perform a full examination, and follow-up with an in-depth discussion about your pet’s condition, ensuring your questions are answered. Together, you and our specialist will discuss the possible treatment options and decide what is best for your pet and your family.

Pet-timonials

Love notes from our special patients.
So great. Took the hound in for a knee surgery and couldn't be happier with the whole process. I can tell they genuinely care for their patients. Very professional, knowledgeable, and compassionate. Little dude is still working on recovery and thanks to OREV, should be running around better than new in no time.

Incredible service. We took our 13-year-old lab here after a routine check-up and our vet discovered a cancerous tumor. The staff had great communication and always had a great attitude. I genuinely felt they cared for our Kottin girl and they'd be sure to treat her well. They did fantastic. Highly recommend OREV.
Tiffany Miller
We came here from out of state and OREV did a CT scan as our regular oncologists' office couldn't at the moment down the road. They were EXTREMELY helpful in getting us on the schedule as quickly as possible. they had great communication for all my questions and concerns. We would highly recommend OREV.
