Music has always been an important part of Christopher Duffley’s life.

“Music to me is for one thing: it brings joy to people. Singing is a gift that I share. Because I’m blind, I see people with my heart for who they truly are instead of what they look like on the outside,” the 15-year-old told ABC News.

Christopher learned how to communicate with others through his love of music.

“It was the music therapy where we realized that he really had talent, that he had perfect pitch, that the harmonies we heard were definitely a gift that he had,” Christine, Christopher’s man, said.

Christopher has since performed for NASCAR, the Boston Red Sox, at national political debates and even during Pope Francis’ visit to Philadelphia in 2015.

“I like singing because when I’m at an event, I know that it brings joy to people,” Christopher explained.

Christopher hosts a weekly “Mission Possible” podcast as a way to connect with fans and to encourage others living with disabilities to dream big. He even edits and engineers each podcast.

Christopher has the same dreams and aspirations. He’s no different, he just does things differently,” Christine said.
