To signify the four-state region of Kansas, Missouri, Oklahoma, and Arkansas the club was named "Heartland Equestrian Organization." Gradually the club's activities began to focus on jumping and dressage. In 1991, HEO joined the United States Dressage Federation as a group Member Organization. Then in 2002 to modernize the name for the idea of all Olympic disciplines we became Heartland Sporthorse Association. This affiliation helps to expand the competitive and educational opportunities available to H.S.A. members.
Our main purpose is to help build a strong foundation of horsemanship by developing and encouraging enjoyable, beneficial , and affordable learning opportunities in the 4 state area. HSA offers local dressage and sport horse activities, publishes a monthly newsletter that covers USDF Regional activities, and provides regular scheduled meetings.
In1988, a diverse group of riding enthusiasts gathered in southeast Kansas to talk about an English riding club. Western pleasure riders and barrel racers rubbed shoulders with dressage and hunt-seat riders. There were a lot of opinions about the goals of the club, but everyone agreed that the main purpose was to have fun while learning better horsemanship skills.
