Although, Mary Kate Green was born in South Side Chicago, she and her family moved to North Western Montana when she was two years old. She spent the next twelve years, living off the grid with her parents and three sisters, on Government Mountain. As a kid, she spent countless hours gathering firewood, picking wild huckleberries, cleaning chicken coops, riding horses, building forts, and simply getting lost in the mountains.
Years later, she took these skills and became a firefighter for the Tahoe National Forest. It was there that she learned, no matter how physically demanding a challenge might be, her mental toughness can always help her complete a job. Mary Kate currently resides in Homer, Alaska, where she is fitness trainer at the Alaska Training Room and a mother to two beautiful girls: Boden Kate and Greta Tuff.
