In 1999 Donavan started us on this journey to breed and assist others to breed, the highest quality warmblood horses for FEI level sports and for pleasure that embody Donavan's kind and affectionate temperament, his natural talent and striking beauty. These offspring are suitable for both the amateur and professional rider. Donavan's long, successful dressage career has demonstrated that he represents the best qualities of the Hanoverian breed, and consequently, the characteristics desired by all warmblood breeds. He absolutely fulfills the goals of the American Hanoverian Society and the German Hanoverian Verband.

Rosall, our wonderful young Oldenburg stallion, has come into our lives to add another dimension to our program, complementing the Donavan mares, and bringing another excellant choice to the American Breeder.  After earning top stallion honors at his 30 Day test in Germany, he came to the US to be ridden by JJ Tate. He has hit the ground running with high Performance scores and awards in his first year of US competition. He carries one of the top Dam lines in Germany in his pedigree. He , too, is a stallion with an endearing personality, and gentle nature. His first two foals re due in 2009, and we look forward to some little Rosalls in the pasture.  Visit Hassler Dressage for video, as well as youtube for Rosall.
