"Hero" best describes Kirstie Ennis. She joined the Marine Corps at just 17 years old. Over the years that she served, she performed duties as a helicopter door gunner and airframes mechanic.

On June 23, 2012, during her last deployment to Afghanistan, her helicopter went down. As a result of the crash, she sustained multiple injuries, including those to her back, face, and brain.

After more than 40 surgeries, she has accomplished more with one leg than most people will ever do with two. Kirstie competed as a Paralympic snowboarder and then ventured into mountaineering, where her goal is to complete the Seven Summits by the end of 2021.

Kirstie also serves people through the Kirstie Ennis Foundation, giving back to thousands of people annually with monetary gifts and refurbished prosthetics.
