The Green Balloon Foundation is a non-profit organization that was founded to help provide financial and end of life assistance for terminally ill patients.
The Green Balloon Foundation title comes from a conversation the Founder, Nick Shields, had with his mom (who passed in 2009, from a rare case of early-onset Alzheimer's). They were at church one Sunday and the theme of the pastor’s sermon was Heaven. The pastor talked about how he believed you may or may not recognize your loved one when you go to Heaven. Nick and his mom didn't like this and thought that they'd, "cheat the system.”
She told him, "When you get to heaven, you'll know it's me because I'll have a balloon in my hand." Nick followed up by randomly asking her what happens if others happen to have balloons in their hand. Nick then asked if it could be a green balloon.
