One Mission was created after Ashley Haseotes’ (President and Founder) journey with pediatric cancer. In 2006, Ashley’s infant son was diagnosed with AML – a rare form of leukemia. His diagnosis called for him to be hospitalized for 188 straight days. During the time Ashley and her husband lived with their son at Boston Children’s Hospital, she became aware of the many emotional and financial needs of the families that were not being met by the hospital. After witnessing so many families struggle to make ends meet, Ashley was inspired to start a foundation that would make life better for children and their families living with cancer.
