From the website-- Since 1980, the Make-A-Wish Foundation has enriched the lives of children with life-threatening medical conditions through its wish-granting work. The Make-A-Wish Foundation was founded in 1980 after a little boy named Chris Greicius realized his heartfelt wish to become a police officer. Since its humble beginnings, the organization has blossomed into a worldwide phenomenon, reaching more than 250,000 children around the world.
