Jim Withers at Gel Health 2009

Concierge healthcare for the homeless: Bringing healthcare directly to the homeless, as Dr. Jim Withers describes in this Gel Health talk, is difficult but rewarding. As a founder of the global street medicine movement, and the subject of the documentary "One Bridge to the Next," Dr. Withers has accomplished a great deal - both in his home city of Pittsburgh with Operation Safety Net and throughout the world in dozens of cities now maintaining street medicine practices.
