WHY WE DO THIS
Cancer Can Steal Childhood. Together, We Help Give It Back.
When a child is diagnosed with cancer, life changes instantly.
Hospital rooms replace playgrounds. Treatment replaces routines. Childhood becomes interrupted by fear, uncertainty, and long days that no family should ever face alone.
That’s why One Mission exists.
Through art and music therapy, holiday celebrations, financial assistance, hospital support, and family-centered programs, One Mission helps children and their families experience moments of joy, comfort, and connection from diagnosis through recovery and beyond.
Your support turns difficult days into brighter ones.

THE STORY
In 2008, Ashley and Ari Haseotes founded One Mission after their infant son Nicholas was diagnosed with a rare form of leukemia at only seven months old.
Nicholas endured 188 straight days of treatment.
During those long hospital stays, Ashley documented everything families needed but often lacked — comfort, connection, support, distraction, and joy.
Those notes became One Mission.
Today, One Mission transforms pediatric cancer treatment experiences for countless families through practical support and moments of hope when they are needed most.
