As a child, Stacy was always trying to get inside the horse's head. When she was 13, she got her first horse, Bay, and rode him to work every day. When Stay turned 16 she began to compete in many events, including jumping and barrel racing. In high school, she found a college where she could major in equestrian studies, the University of Findlay in Ohio.
In 1994, while at the All American Quarter Horse Congress, Stacy met her future husband Jesse — himself a talented reining trainer. They married three years later and then established the Westfall Horsemanship training facility in Mt. Gilead, Ohio. They have three young boys, Caleb, Joshua, and Nathan.
Stacy has grown to become one of the country's top clinicians and competitors. She currently tours the country offering clinics and making educational appearances at expos and equine events.
