His approved son , young stallion Royal English KIS in his Dressage debut with Katie Hiller, showing his kind temperament and Rusty is now eventing with his young rider. They get such wonderful temperament and also talent in several areas from their sire.

rosall Kent Island Sporthorses has long supported their trainer, JJ Tate, and wished to try to help her reach her Olympic goals. JJ set out to find the ideal stallion with the right combination of talent, temperament, character, and pedigree that Marty and Wendy Costello would own and manage, but JJ would compete. JJ heard about the Oldenburg stallion, Rosall, through Oded Shimoni. Rosall was actually was being ridden by a friend of JJ’s at Katrin Burger’s, rider of French Kiss and Daydream. After viewing his videotape, JJ fell in love with Rosall’s canter. She made the trip to meet Rosall (barn name “Riley”) in the Fall. He was purchased and the Costello’s opted to leave Rosall in Germany until the completion of the 30 Day Stallion Performance Test.

    Once Rosall finished his 30 Day Stallion Performance Test in Munich-Reim, he would come to the U.S. In the Spring of 2007, after becoming the Champion stallion at his testing, Rosall arrived in Maryland! Since then, Rosall and JJ have been strong on the competition circuits, winning many of their classes from Training to Third Level and earning the 2008 USEF All Breed First Place Award for the GOV at Training Level.

    In early 2009, Rosall was the Champion Stallion of the first-ever 10 Day Advanced Stallion Performance Test organized by ISR/Oldenburg, NA. Held in Jupiter, FL at the Lady Jean Ranch, Rosall earned an overall 129 points and a lifetime license with the registry. He received 9’s on character, rideability, willingness to work and from his test rider, Mikaela Gunderson! (video)
