Oklahoma City Equine Clinic



Oklahoma City Equine Clinic was established in 1990 by Doctors Brian Carroll, Dee Gragg, and Larry Powers. OCEC is a full-service equine clinic serving Oklahoma City and surrounding communities. The clinic is located on 24 acres within 10 minutes of the Oklahoma State Fairgrounds and Remington Park Racetrack. In 2008, the clinic underwent an extensive remodel to improve our hospital stalls, the climate controlled intensive care unit, pharmacy and office areas. OCEC also houses offices for our sister company, Embryo Transfer Services L.L.C.

Oklahoma City Equine Clinic is dedicated to providing a team of veterinarians and support staff committed to the highest standards of veterinary care for horses of all shapes and sizes. In pursuit of this goal, we provide the following areas of service: medicine, surgery, performance/lameness, ambulatory/emergency, and reproduction. With this diverse directory of services, OCEC is able to provide exceptional care from conception to performance to production.

Dr. Brian Carroll

Dr. CarrollDr. Carroll grew up in rural east central Oklahoma and attended Oklahoma State University for undergraduate work, as well as, obtaining his D.V.M. Since graduating in 1980, his general equine practice has included emphasis on western performance, sport horse, race track practice, and farm medicine. However, since 1994 his practice time has been spent primarily in reproduction. Today Dr. Carroll's days are spent working in assisted reproductive techniques for the mare and advanced stallion management.

Caitlyn Hood

CaityCaitlyn, originally from southwestern Oklahoma, attended Oklahoma State University completing a B.S. in animal science in 2007. She joined the OCEC team in October 2007 as a general hospital technician. Soon realizing her interest in reproduction, she began to assist Dr. Carroll with his ambulatory breeding work in January 2008. Before long, she demonstrated a strong aptitude for laboratory skills and intense attention to detail. These qualities have served her well as she has excelled in advanced semen processing techniques such as cushioned centrifugation and density gradient centrifugation in order to integrate them into chilled transported and semen freezing protocols. When not working, she enjoys showing hunter/jumpers.
