PHOENIX - The Phoenix Walk For Wishes returns for another year to celebrate wishes and fundraise for future wishes granted by the Make-A-Wish Foundation.

As a prelude to the event, the mother of the first "wish child," Linda Pauling, shared her story, hoping to inspire others to donate to a life-changing cause.

Linda’s son, Christopher Greicius, was diagnosed with Leukemia in the late 1970s.

“Christopher was a good little boy,” recalls Linda. "We just had fun together, he was my little buddy.”

He always wanted to be a police officer, so in his last month, a family friend helped make Christopher’s wish come true with a show-and-tell with a Department of Public Safety trooper.

That was the last week of his life and the beginning of the Make-A-Wish Foundation.

After 36 years, the grassroots organization has granted thousands of wishes to kids with a life-threatening condition as well as those terminally ill.

Everyone can help keep a legacy alive by donating money or volunteering time.

Linda knows, “the parents remember the wish, the happiness, and they hold on to this and all the memories.”

The Make-A-Wish Foundation's 2016 Phoenix Walk For Wishes is this Sunday. The one-mile fun run and walk will be at Tempe Marketplace, with check-in at 7:30 a.m.
