To the outside world, the glitz of South Beach is Miami, but beneath the plastic veneer, we've got ourselves one of the poorest and neediest metro areas in America. What's worse, out of the 50 biggest cities in the U.S., we volunteer the least. Even people in that other Sin City (Vegas) give more of their time than we do. Still, there's a lot of good going on in Miami, and perhaps there's no better example of that than the charity Voices for Children. Founded in 1984, the foundation recruits, trains, and supervises adults who act as representatives and guardians in court for the nearly 4,000 children who are in Miami-Dade foster care. The foundation (recently given the top four-star rating by the national charity evaluator charitynavigator.org) also helps take care of additional needs for foster children, such as clothing, eyeglasses, and educational activities. Since its inception, Voices for Children has represented more than 25,000 children.
