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.
