The Harris Staff has exceptional credentials and have worked as a team for many years.

John C. Harris-President and Chairman of the Board

jchatriverrJohn has been involved in the Agribusiness and Thoroughbred business all of his life. Harris Ranch has been in continual family operation since the turn of the century and is now one of the largest Agribusiness in the nation.

In addition to the various Harris Ranch Companies cattle and agribusiness operations, the Harris Farms Horse Division ranks as one of the country’s leading racing stables and is one of the thoroughbred industry’s most influential owners/breeder operations.

Harris has bred and raced numerous outstanding horses including 1994 Cal-Bred Horse of the Year, Soviet Problem, a filly who came within inches of winning the ’94 Breeders’ Cup Sprint.

Harris has served five terms as President of the California Thoroughbred Breeders Association and is currently serving on the Executive Committee as past President.

Since 1994, Debbie has been the Administrative Assistant to the Chairman/CEO of Harris Farms, John. C. Harris. She is depended upon for a large variety of assignments and is a very valuable part of the team.

Jonny Hilvers-General Manager Horse Division

Jonny grew up at Old English Rancho and has a great background for thoroughbred ranch management. He worked alongside his grandfather and racing Hall of Fame member, Buddy Johnston, as a youth. Jonny was groomed for leadership prior to Buddy’s unexpected passing in early 2015. He has performed every farm job from breeding, foaling, and vet technician to nutritionist, training, racing, etc.

“Jonny Hilvers will be a key ingredient to all of the mutual success I envision,” said John Harris. “He brings us solid leadership and practical excellence and represents a new generation to help lead California forward.”
