An avid outdoors enthusiast, Kathy enjoys horseback riding, hiking, cross country skiing and rafting. She also loves spending time in her orchard, preparing and sharing meals with family and friends, and the occasional ping pong game with her husband, Steve. Kathy has instilled her passion for an active lifestyle in her four children, too. Two of her sons are Personal Trainers, one is in school training to become a Physical Therapist, and her daughter is a Yoga instructor. Lucky for us, we’re pretty sure Kathy is in the Methow for the long run!
