to get kids through cancer

Here to do whatever it takes

Who We Are

Helping kids and families get through cancer treatment – one day at a time.

One Mission is a pediatric cancer charity that does whatever it takes to get kids through cancer.  One Mission programs make living in the hospital less lonely and stressful, bring back joy in a time of fear and uncertainty, and give kids and their loved ones the support they need to get through the emotional and financial challenges of treatment.  All of the programs we fund directly benefit children and adolescents diagnosed with cancer, the families who support them, and the medical community who compassionately cares for them. These programs and services rely exclusively on philanthropic support as they are not reimbursable through insurance or eligible for traditional grant funding.

Since 2009, One Mission has raised more than $8.8 Million dollars and has brought smiles, comfort and support to over 8,000 kids fighting cancer and their families.

Our story

Few things are more devastating than hearing the news that your child has cancer. Children and parents are thrust into a frightening situation for which they are totally unprepared.  The founders of One Mission, Ashley and Ari Haseotes, understand full well the devastating impact of pediatric cancer. One Mission was born out of their own family’s journey with cancer.  At seven months old their son was diagnosed with AML, a rare form of leukemia.  They spent six months living at Boston Children’s Hospital, their lives turned upside down.  Thanks to the compassionate care and expert treatment their son received, today he is cancer-free. During their journey, they identified many ways life could be improved for patients and families during treatment and hospitalization.  Their experience inspired them to start a foundation that would address those needs and make life easier for pediatric cancer patients and their families.
