The MMSC began as a visionary project in conjunction with the Kentucky Horse Park and racing industry to showcase to the world the athletic abilities and talents of the American Thoroughbred. With thanks to the generosity of Castleton Lyons Farm, Eaton Sales,  Keeneland, Mary Lou Whitney, her husband John Hendrickson, Maker's Mark and the Thoroughbred Retirement Foundation, the MMSC opened its doors in October of 2004. It is comprised of 20 acres of paddocks, a ten-stall barn, an outdoor arena, a round pen, a Hitchcock pen, and a small cross country course. At any time it houses 10 to 20 Thoroughbreds all in different phases of the Horse Centered Re-Schooling Program (SM), all available for adoption.

The MMSC is keen to provide education for former racehorses to move on to new careers. We stand as a beacon for those interested in learning about reschooling horses and specifically about the assets and virtues of the remarkable Thoroughbred breed. Thanks to the generosity of Mr. and Mrs. Leonard Riggio, owners of Barnes & Noble and devoted fans of Thoroughbred racing, the MMSC enjoys a collection of resources on training horses in its Bucephalus Training Library. We have educational opportunities from high school through college for volunteers and for public groups.

The MMSC is open to the public from Tuesday through Saturday from 9:00 to 2:00 (hours may change during the winter months).  Visitors are welcome to tour the facility, watch training sessions, or use the library. To try a horse as a potential adoption candidate, individuals must first fill out the MMSC adoption application
