About Us

RCS strives itself on top of the line nutritional and managerial services and provides customers with a stress-free and enjoyable escape from everyday life regardless of their preference for showing or pleasure riding.

In 2018, Courtney Tjeerdsma moved back to South Dakota after receiving her Bachelor of Science in Equine Science and Management at the University of Kentucky.
