Massa Sporthorses is a 20-acre sport horse breeding facility located in Northern, California. Duane and Wendy Massa stand a small group of Hanoverian mares specially selected for their temperament, movement and ride-ability. We breed to sires with top European bloodlines carefully selected to complement each mare. As breeders of sporthorses our objective is to produce high quality, well-bred and well-mannered riding horses for sport and for pleasure. We offer a few horses for sale each year.
