I am a lifelong horse lover and equestrian athlete. I retired as a medical technologist to follow my dream of becoming a horse trainer, a personal trainer, and a yoga instructor. I have competed several horses in Dressage, winning multiple year-end and series awards, including first level with “Letter to Elise” at the 2003 Virginia State Horse Champion Schooling Shows. I have also competed in numerous 5K, 10K, 15K, 10 mile and half marathon races. Physical fitness and strength training have positive effects on my riding and I am excited to share this with others.
