Dr. Jim Withers is a doctor and resident in the city of Pittsburgh, Pennsylvania. Every two or three times a week, he leaves his home at night, disguises himself as a homeless man and he visits places that most people would avoid. There, Withers has been searching for the homeless to offer them free, quality medical care for those who need it.
He does that for 23 years now and he calls it "street medicine." "I was actually really shocked how ill people were on the street. It was like going to a third-world country," Withers said. "Young, old, people with mental illness, runaway kids, women (who) fled domestic violence, veterans. And they all have their own story."
With an indomitable will to help more, Withers also initiated a non profit organization called the Street Medicine Institute, which supports communities in starting their own medical programs for the homeless. You can vote for Dr. Withers as your choice to be Hero of the Year at CNNHeroes.com.
