John and Mark X. Cronin are the dynamic father-son team behind John's Crazy Socks, a social enterprise with a mission to spread happiness. They bootstrapped their business into the world's largest sock store with multi-million dollar revenues, and won Ernst & Young's Entrepreneurs of the Year in 2019. What makes their story particularly special is that 27 year-old John has Down syndrome, and is constantly challenging preconceptions about differing abilities, exemplifying the remarkable achievements that can arise when inclusion takes centre stage.
