"My gang mates were the most influential thing in my life," says Fajardo, who joined a gang when he was in sixth grade. "We were pressured to join."

He's not alone. In the Philippines, teenage membership in urban gangs has surged to an estimated 130,000 in the past 10 years, according to the Preda Foundation, a local human rights charity.

"I thought I'd get stuck in that situation and that my life would never improve," recalls Fajardo. "I would probably be in jail right now, most likely a drug addict -- if I hadn't met Efren."
