Kiara Clark, 11, from left, Annie Odrowski, 13, and Kiara’s mother Beth Clark plan for the Gynormous Garage Sale on Saturday at Raintree Montessori School, 4601 Clinton Parkway. Kiara and her friend Imalia Gansop co-founded the nonprofit Kids Committed to Kids when they were 8, and three years later, their fundraising efforts are still going strong.

They’re two little girls with a big goal, and even though they’re only 11, they’ve already been involved in putting on fundraisers for several years.

Kiara Clark and Imalia Gansop created the nonprofit Kids Committed to Kids in 2005. And despite losing one of its co-founders — Gansop and her family moved away — the organization is still going strong.

“To hear them tell it, the moms came up with it. To hear the moms tell it, the kids came up with it, so I think somehow it was a joint effort,” Kiara Clark’s mother, Beth Clark, said. “However it happened, they were thrilled and delighted, and they ran with it.”

The girls first came up with the idea to raise money for kids in 2005. Their first event, a benefit garage sale in October of that year, raised about $3,400, with half going to Big Brothers Big Sisters of Douglas County and the other half to children affected by Hurricane Katrina.

In 2007, they put on a car wash and successfully raised another $1,200, which they donated to Van Go Mobile Arts and Global Action for Children, to improve the lives of children in Africa.

“Me and my friend were so passionate about kids,” Raintree Montessori sixth-grader Kiara Clark said. “They really deserve a healthy life, and they deserve food, an education and shelter. They deserve that kind of stuff.”

Saturday they’ll be back at it again, putting on what they call a “gynormous” garage sale, hoping to raise money to fund breast cancer research. Gansop is coming all the way back from Minneapolis to attend the event.

“It could happen to your mom, and it could happen to your sister, and it could happen to them when they grow up,” Beth Clark said. “They saw it as an issue that’s going to affect kids no matter what happens, and so they wanted to do something about it.”

The girls, along with dozens of volunteers, are hoping to raise $7,000 — the amount three local women need to come up with to walk in the Susan G. Komen three-day event to raise money for breast cancer research.

“We could never do this without their help,” Susan Cary said. She and her friends Julie Embrey and Shari Anderson hope to travel to Chicago in August to take part in the 60-mile walk in memory of their friend Amy Laughlin.

Laughlin, who owned Second Chance Children’s Clothing in downtown Lawrence, died in November after a 12-year battle with breast cancer.

“It’s just amazing,” Cary said. “These kids have the energy. They didn’t even really know Amy, and yet they just don’t want this to happen to another kid’s mom. Their hearts are as big as anything.”

The Gynormous Garage Sale will run from 6 a.m. to 3 p.m. Saturday at Raintree Montessori, 4601 Clinton Parkway. In case of rain, the event will be inside Bishop Seabury, 4120 Clinton Parkway.

Volunteers will be accepting donations for the garage sale from 6 p.m. to 9 p.m. today at Raintree.
