Marine Sgt. John Peck survived an IED during the War on Terror that left him with a traumatic brain injury, amnesia, and cost him his marriage. He survived another three years later, one that left him with three and a half limbs missing. He's one of only two living people to survive the flesh-eating fungus he contracted in recovery at Walter Reed, one that left him as a quadruple amputee. And that's only the beginning of his story. What followed was a recovery nothing short of miraculous. With resilience and the help of advocates like actor and philanthropist Gary Sinise, FOX's Jennifer Griffin, and Bill O'Reilly, John would use a specialized "Action Trackchair" wheelchair and a newly-built SmartHome to get a third lease on life. In 2016, Peck underwent a groundbreaking bilateral arm transplant, receiving two new arms.
