 Volunteers who saw the story said they wanted to help build these life-changing chairs. So Platt put some to work. And with his team at Tulane University, they built all these chairs, about 25, in just the last five months. Look at little Ellie's elation. Come on! Come on! The smile on Theo's face. You can do it! Come on! And just imagine what little McKenna might be thinking. Come on! Come on!
