When Julie talks about her son Tyler’s experience at Camp Quality, she remembers everything from friendships to ceramic projects to the smile on her son’s face when he comes home at the end of the week.

“It’s just a great place for these kids that have had to go through the stuff that they don’t even realize they don’t have to do — the shots three times a week, hospital every month, spinal taps every week,” she said.

Campers arrive Sunday at Camp Farwesta in Stewartsville, Mo., for this year’s event, which runs June 8 to 13.

Camp Quality is a weeklong, community-funded camp for children who have been diagnosed with cancer. The camp is open to children who have been treated at Children’s Mercy Hospital in Kansas City.

After hearing about Camp Quality from Tyler’s doctors and nurses, Julie said she finally decided to let her son go as a 6-year-old, right after he finished the biggest part of his treatments. Tyler will return next week for his sixth consecutive visit, and Julie still remembers his first experience.

“I finally called out to camp Wednesday night and said, ‘Would you please make Tyler call me?’” she said. “He was too busy and having too much fun to even think about calling me.”

Camp Quality policy does not allow campers’ last names to be released to the media.

From the minute they hit the ground, each camper is paired with a weeklong companion — a volunteer who has gone through eight hours of training. Tyler’s companion was once a camper and has now returned to see the other side, which is something that Tyler already has decided he wants to do in six more years.

“He thinks the world of his companion,” Julie said.

Lynett Bingaman, who runs the camp’s country store and post office, said volunteers range in age from 17 to 80 and hail from as far away as Florida and New York.

“As a volunteer, you take away far more than you give,” she said of the experience.

Ms. Bingaman said big events this year include a performance by country singer Kevin Sharp, a visit from actor and movie director Georg Stanford Brown and a performance by a group of Chinese acrobats. Camp Quality can host up to 115 children and already is expecting about 100 next week, a number camp director Tom Brand said is on par with last year’s number.

“With that group that we’re seeing, we realize that eventually there may be a possibility that we may grow just beyond one week,” he said.

Mr. Brand said a weekend camp also is in the works.
