CAVITE CITY, Philippines (CNN) -- At 16, Rhandolf Fajardo reflects on his former life as a gang member.
Efren Peñaflorida's Dynamic Teen Company offers Filipino youth an alternative to gangs through education.
"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."
"Gang members are groomed in the slums as early as 9 years old," says Peñaflorida. "They are all victims of poverty."
For the past 12 years, Peñaflorida and his team of teen volunteers have taught basic reading and writing to children living on the streets. Their main tool: A pushcart classroom.
Stocked with books, pens, tables and chairs, his Dynamic Teen Company recreates a school setting in unconventional locations such as the cemetery and municipal trash dump.
Peñaflorida knows firsthand the adversity faced by these children. Born into a poor family, he lived in a shanty near the city dump site. But he says he refused to allow his circumstances to define his future.
"Instead of being discouraged, I promised myself that I would pursue education," he recalls. "I will strive hard; I will do my best."
In high school, Peñaflorida faced a new set of challenges. Gang activity was rampant; they terrorized the student body, vandalized the school and inducted members by forcing them to rape young girls, he says.
"I felt the social discrimination. I was afraid to walk down the street."
Peñaflorida remembers standing up to a gang leader, refusing to join his gang. That confrontation proved fateful. At 16, he and his friends "got the idea to divert teenagers like us to be productive," he says.
He created the Dynamic Teen Company to offer his classmates an outlet to lift up themselves and their community. For Peñaflorida, that meant returning to the slums of his childhood to give kids the education he felt they deserved.
"They need education to be successful in life. It's just giving them what others gave to me," he says.
Today, children ranging from ages 2 to 14 flock to the pushcart every Saturday to learn reading, writing, arithmetic and English from Peñaflorida and his trained teen volunteers. Watch Peñaflorida and his group in action with their push cart classroom »
"Our volunteers serve as an inspiration to other children," he says.
The group also runs a hygiene clinic, where children can get a bath and learn how to brush their teeth.
Since 1997, an estimated 10,000 members have helped teach more than 1,500 children living in the slums. The organization supports its efforts by making and selling crafts and collecting items to recycle. Take a look at the slums where Peñaflorida and his group spend their Saturdays »
Through his group, Peñaflorida has successfully mentored former gang members, addicts and dropouts, seeing potential where others see problems.
"Before, I really didn't care for my life," says Michael Advincula, who started doing drugs when he was 7. "But then Efren patiently dug me from where I was buried. It was Efren who pushed me to get my life together." Watch Advincula describe how he met Peñaflorida in the slums »
Today, Advincula is a senior in high school and one of the group's volunteers.
Peñaflorida hopes to expand the pushcart to other areas, giving more children the chance to learn and stay out of gangs.
"I always tell my volunteers that you are the change that you dream and I am the change that I dream. And collectively we are the change that this world needs to be."
