 Here comes Mr. Sam. Sam is a smiling, wiggly six-year-old who loves to dance. Today, he's chosen to wear a purple T-shirt with a roaring blue T-Rex across the back. Oh, he's a dinosaur fanatic. Sam has significant disabilities, including Crete-A-Shaw syndrome, a rare genetic disorder. He mostly gets around using a wheelchair. Sam's also partially deaf. His primary language is American Sign Language, or ASL.
