  • Bella Mowbray-Stevenson

    Head Trainer

    Bella began her riding career under the careful eye of her dressage trainer mother, Camilla, and dressage judge grandmother, Mary. Bella's natural talent and passion for the sport was evident throughout the years as she quickly became one Australia's top Three Day Eventing riders, competing and winning many 4**** events throughout her childhood and early adult years. Upon developing her business, Mowbray Sport Horses, in the United States, she transitioned her focus to the Hunter/Jumper/Equitation disciplines. Bella's multidisciplinary background gives her a unique advantage as a coach and trainer, allowing her to see each horse and rider from various perspectives. Beyond the stables, Bella is the proud mother to her two young children, Oskar and Roo.
