Chicago's doctor to the homeless

Dr. Patrick Angelo is an oral surgeon by day in the Chicago area, and drives into the city several nights a week to help the homeless. A successful physician with a house in the suburbs and children of his own, he says it came to him like a flash that he could do this and make a difference. So he packed up, though not sure where to go and what to do, and off he went. That was 13 years ago, and he has been doing it ever since. (Reuters)
