Mary White makes house calls. She's a senior community health worker in Philadelphia in the IMPaCT program at the Penn Center for Community Health Workers. She has 25 of the University of Pennsylvania Health System's toughest patients. It's her job to help them set health goals and, step by step, carry them out.
One of her patients is Grover Wilson, an engaging man of 56 who weighs 515 pounds. Wilson had long been athletic and sociable, the organizer of a long-running community volleyball game. But depression and an injury led him to gain weight. Now he lives in a tiny basement apartment packed floor to ceiling with boxes of his possessions, and is trapped and isolated by his weight.
