ARDMORE, Okla. (KXII) - The program is called Youth Force.
"Our main mission is to share God's love and bring hope to the world," Volunteer Ella Kate King said.
It's made up of a group of teens from middle school, high school and a few college students from Methodist churches all over Oklahoma that volunteer a week in the summer repairing houses in selected cities.
This year 150 volunteers are in Ardmore staying at the First United Methodist Church.
They are repairing six homes and one church.
"Just to see the way you change your home owners lives over like a four day time period, you do get changed as a person," Volunteer Grace Livsey said. "You become more humble."
13-year-old Ella Kate King and 16-year-old Grace Livsey say they've been working on a house on East Main Street since Sunday - building a ramp, repairing the deck and painting it, adding siding around the home and fixing up the roof.
"It's just so much fun to see how you change somebody's life and how you could be that blessing," King said.
And the life they are changing is the grandmother of 13-year-old Ayanna Liggens.
"She actually needs something that's new in her life and something that makes her feel good inside that people come around and help her," Liggens said.
Liggins says her grandmother now has a ramp to get inside her home safely and a roof that won't leak every time it rains.
"Thank God that they're here to help us because if we didn't have them she wouldn't have this right now," Liggens said.
"It's just so cool to drive by one day and realize I actually helped that person and I changed their lives," Livsey said.
A director of the group says about $33,000 was collected just from the registration fee volunteers have to pay to participate to go towards buying the supplies.
