Marion DuPont Scott Equine Medical Center


Virginia Tech’s Marion duPont Scott Equine Medical Center is a premier, full-service equine hospital located in Leesburg, Virginia, and one of two hospitals of the Virginia-Maryland College of Veterinary Medicine. The equine center offers advanced specialty care, 24-hour emergency treatment, and diagnostic services for all ages and breeds of horses. As a campus of the Virginia-Maryland College of Veterinary Medicine, the center was one of the first university veterinary hospitals in the eastern United States to concentrate exclusively on equine medicine and research. In its first three decades of operation, the center established a reputation for excellence in emergency care, surgery, and diagnostic imaging, most notably at the forefront of discovery and scholarship in the area of colic.

Just a short drive from the major stables, courses, and tracks in both Virginia and Maryland, the hospital now sees more than 2,500 patients annually and has a renewed focus on emergency and critical care, sports medicine, regenerative medicine, and neonatal and reproductive services. The center serves the region’s private practitioners by working collaboratively to diagnose and treat cases and by providing opportunities for advanced continuing education. The center also provides specialized training for residents, interns, and veterinary students.
