At 14, David Sanchez was on the way to his after-school restaurant job when he saw a homeless man holding a "Will Work for Food" sign. Later, David decided he wanted to give him his tips, but he never saw the man again. "That experience bothered me," he says, motivating him to launch Job-Link Racine to help homeless and at-risk teens find work. Since 2008, David, now a senior, has taught readiness training to more than 300 teens, secured interviews for 60, and helped 30 land jobs in a tough economy. He also donates bus tokens and work clothes. "They are no different than I am," he says. David will attend Vanderbilt University this fall.
