Dunkerton Eventing is operated on our privately owned, 20 acre farm, in Chattahoochee Hills, GA. We specialize in training OTTB’s, Adult Amateurs, and Young Riders. It is our mission to work with goal oriented riders at all levels, helping gain a deeper understanding of horsemanship and expanding on your natural skill set and style. From learning to walk/trot/canter, aiming for Young Riders, or working up the levels, we take a personal approach to each individual. Not only to help your progression, but to focus on understanding “the why” behind the questions, instruction, and reactions, in the horse and jockey relationship.
