I Share Hope: Chris Williams

Sean Swarner is a two-time cancer survivor who, both times, was given just weeks to live. He not only survived but thrived. He became the first cancer patient to summit Mt. Everest and he didn't stop there in his desire to motivate and inspire. He went on to climb the highest peak on each continent, then completed the Hawaii Ironman Triathlon and, in January, made a successful trek to the South Pole. He is also the founder of nonprofit cancerclimber.org; is the author of Keep Climbing; and has been dubbed one of the most inspirational persons of all time. This year, he celebrates 25 years cancer free.
