Doniphan Stone survived cancer at the young age of 15. He not only survived it, but he regained his strength and became a Junior Olympic medalist in Taekwondo and played Division II collegiate soccer.
Today, he is the co-author of the book Fearless Devotion, which is about creating and achieving your goals from the inside out. He is also the Co-President and Founder of Corefirst™ and created the original Corefirst training system.
To say that Donny is an ‘overcomer’ seems like an understatement. I am confident Donny’s story will inspire you today.
