    Dr. Marina Santos

    Marina is from Brazil and earned her Doctorate of Veterinary Medicine degree from the Federal University of Viçosa. In 2022, she moved to the United States to pursue further training, beginning with an internship at Purdue University, followed by a surgical fellowship at the University of Pennsylvania (UPENN). She is excited to gain more experience in large animal surgery as her long-term goal is to pursue a surgical residency. Outside of work, she enjoys reading, watching movies, and exploring new places with my husband and friends. Her favorite part of being an equine vet is building relationships with horses and horses’s owners.

    Dr. Ashlyn Morris

    I am from Poteau, Oklahoma. I completed my undergraduate studies and veterinary school at Oklahoma State University (go pokes!). In school, I was involved in the American Association of Equine Practitioners, American Holistic Veterinary Medical Association , Society for Veterinary Surgery & Anesthesiology, SAVMA, and Operation Catnip - free TNR program. I plan to apply for a surgical residency this fall and eventually end up as a clinician & professor at a veterinary school. In my free time I enjoy reading, spending time in the sun, traveling, watching football and being around my dogs & horses!
