Marie’s love for animals began as a child. Her first dog came into her life at the age of seven and a horse by 18. At the young age of 7, the lifetime adventure of training and competing with dogs began. Fast forward many years later and she has competed in agility all over the country, including regional and national events, earning spots on the podium many times. She has trained her dogs through the years to earn many titles and awards, not only in agility, but herding, tracking, obedience, dock diving, and conformation. She has recently had a calling to do Search and Rescue with her Belgian Shepherd. She is a volunteer for Minnesota and Wisconsin K9 Search and Rescue Team. She enjoys time with her dogs, horses, family, and friends.
