About Mercedes

Mercedes has had a lifelong passion for horses. She has been riding as long as she can remember starting in her native Argentina, and in everyplace she has lived and visited.
Her goal for River Edge is to create a serene, natural habitat for horses, to provide the best quality service and individual care and management of each horse.

For our riders to acquire horsemanship and riding skills the natural way, by interacting with the horse, by tacking up, grooming, by learning about horses from horses in a supportive environment.

This interaction develops the kind of empathy that is required to achieve mutual understanding and communication between horse and rider.
