John Arbino is not your ordinary hero.

In 2003, while serving as an Intelligence Officer for the US Army, he was diagnosed with multiple sclerosis. After experiencing an exacerbation which made walking difficult, John moved to a wheelchair. But this turn of events only made John more motivated to thrive with his MS.

John calls this moment “the boom” – it’s not what has happened to you but how you react afterwards that’s most important in defining what your life becomes.

Watch the video to learn more about John’s journey and how he was able to not only adapt to his new condition, but go on to win two gold medals and a silver at the U.S. Paralympics Warrior games.
