Please join us in welcoming our newest associate veterinarian to the practice!
Dr. Anastasia Keyser is originally from Texas. Although she didn't grow up on a ranch, her family always had horses, and she was riding before she could walk—a passion that has stayed with her ever since.
Before pursuing veterinary medicine, Dr. Keyser earned a B.A. in Business Administration and spent several years training horses while running a 501(c)(3) horse rescue. She later earned her DVM from Texas A&M University's College of Veterinary Medicine & Biomedical Sciences, where she worked in the Large Animal ICU at the Veterinary Medical Teaching Hospital. She then completed an internship at Reata Equine Hospital in Weatherford, Texas, before spending the past 10 years practicing equine medicine at Chaparral Veterinary Medical Center in Cave Creek, Arizona.
Dr. Keyser enjoys all aspects of equine practice, with special interests in dentistry and sports medicine. She believes that helping horses perform at their best means focusing on every aspect of their health and well-being—not just soundness.
When she's not caring for patients, Dr. Keyser enjoys competing with her horses in eventing and dressage, as well as trail riding, hiking, camping, scuba diving, skiing, and traveling. She also shares her home with 10 horses and four dogs.
We're excited to have Dr. Keyser join the Performance Equine team and look forward to introducing her to our clients!
