The Sturgis Veterinary Hospital opened its doors to the public in 1952 at the reins of Dr. J.A. CHAMLEY and his wife ANNIE. In 1971, current owner DR. JOHN ISMAY purchased the hospital.

Raised by a ranching family in the high mountains of southwestern Colorado, Dr. Ismay is no stranger to hard work. His vision for a high-tech specialty center has resulted in a facility dedicated to raising equine and companion animal medicine and surgery to an ever-increasing standard of excellence.

Located in the Black Hills of South Dakota just north of Interstate 90, the Sturgis Veterinary Hospital & Equine Center has long been a hub of advanced equine and companion animal medicine, surgery and dentistry, providing a referral center for South Dakota, Wyoming, North Dakota, Montana, and Nebraska.
