Neurological disease graduate walks stage with service dog.

Sarah Mendenhall, a recent graduate from the University of Oklahoma, walked across the stage with her service dog, Oliver, by her side. Seven years ago, she was paralyzed from the neck down due to a rare neurological condition known as acute flaccid myelitis. With Oliver's help, she slowly started to move again and fought for each step forward. She graduated with a degree in communications and hopes to work for the Centers for Disease Control and Prevention to make a change for kids like her.
