The O RO's
American Quarter Horses

The RO horses were bred long before the inception of the AQHA. Starting with the Green Cattle Company in Cananea, Mexico when they purchased the O RO Ranch in Prescott, AZ in 1936. At the start of the AQHA, some of the first horses registered were from the O RO Ranch with El Rey RO in the first stud book as #896. We have continued to take pride in our horses and our breeding program. The ranch is honored to be an AQHA Ranching Heritage breeder. In 2019, the O RO Ranch was recognized as an AQHA 75-year Breeder and in 2022 was awarded the Best Remuda.
