The Owners

Margi and Norm Castiglione have extensive experience with thoroughbreds and are the proud owners Prima Showjumpers and Riversedge Racing Stables in Okotoks, Alberta.

After developing an interest in showjumping horses and meeting Piet van Genugten, from the Netherlands, Prima Showjumpers slowly went from just an idea, to a becoming reality. 

Margi's love for horses is second to none and Norm's great business sense and personality form the foundation that Prima Showjumpers stands on.

Piet van Genugten, a graduate of NHB Deurne equestrian college in the Netherlands, is the head trainer and manager for Prima Showjumpers stables.
