Great Oaks Ranch and Vineyard is currently home to sixteen American Quarter Horses. The American Quarter Horse has long been valued for several sporting pursuits and is the primary breed used in the long practiced sport of working cow horse, reining and cutting. These horses are a smart breed that is particularly suited to respond to the subtle hand and leg movement the sport of reining requires. Competitive reining is a demanding sport for both rider and animal. In fact, it requires such a high level of skill and both participants part that it was recently added as a sanctioned event at the Summer Olympics.

Great Oaks Ranch's stable has been planned so there is one group of horses that currently show their value in the ring, and promise a next generation of offspring to carry on that legacy when their days competing are over. There is another group that are producing foals that have the genes of champions in their veins. There have been four foals born through the breeding program at Great Oaks Ranch in the last three years. These are all registered American Quarter Horses. They are already starting to show desirable qualities that will make them attractive to quarter horse buyers once they are trained.

Great Oaks Ranch has developed a stable of horses that will help to build its reputation within the professional circles of the American Quarter Horse and National Reining Horse Associations as well as with the average Quarter Horse enthusiast.

Michael Lippman personally rides the cow horses both at the ranch and competitively. "I find that I get more nervous when someone else is showing my horse," he said. "I prefer doing it myself."
