Serving Southern Arizona for 25+ years
Proudly Serving Tucson since 1994
Southern Arizona Veterinary Specialty and Emergency Center (SAVS) was founded in 1994 by Dr. Mary K. Klein and Dr. Reuben Merideth. At the time, Tucson did not have a multi-specialty veterinary group for patients with multiple or complicated needs. As a result, pet owners were required to travel between several veterinary clinics to care for their animals. The goal of SAVS was to make exceptional veterinary care accessible to local pet owners. In 1994 and today, SAVS is guided by four pillars: patient care, teamwork, education, and excellence.
We are committed to providing the highest level of patient care delivered with compassion.
As individuals, we will treat each other respectfully and communicate to effectively achieve the highest level of teamwork.
By increasing and sharing our knowledge, we will be better tomorrow than we are today.
We will strive to exceed expectations in all that we do.
Growing to meet the demands of our community
In 2006, SAVS opened a clinic on Broadway Road to serve the growing community in East Tucson. Today, SAVS continues to be the top provider of veterinary specialty and emergency medicine in Southern Arizona. Our two clinics in Central and East Tucson offer emergency, surgery, internal medicine, dentistry, dermatology, ophthalmology and oncology by board-certified veterinarians. Growing to meet the demands of our community means we are always looking for talented and compassionate team members. Learn about opportunities to strengthen your career at SAVS on our careers page.
