Riley loves going to summer camp and especially loves playing outdoors. In July 2012, he was diagnosed with idiopathic pulmonary hypertension; doctors told his parents he would probably not live to see his fifth birthday. He is now six, and like many sick children, he lives life with highs and lows. Still, there are enough highs to nourish Riley's hope of one day becoming a doctor himself so that he can help sick people.
