Aspen Snow Ball Week is an annual event framed by our black-tie Aspen Snow Ball Gala. A week-long curation to champion community, compassion, and connectivity. 

Aspen Snow Ball Week attracts influential philanthropists, powerful brands, and entertainers in the pursuit of one common goal to eradicate pediatric cancer. The gala boasts celebrity performances and celebrates honorees making humanitarian and philanthropic contributions aligned with our mission.

COSF funds the development, research, and programs of less toxic therapies for pediatric cancer patients across the nation. Since it’s inception in January 2023 COSF raised over $5 million dollars for pediatric cancer research and wellness programs. The foundation works directly with hospitals and established nonprofits to build partnerships with its core values in mind: transparency, community, and relevancy.

At the 2024 Aspen Snow Ball we announced the launch of an endowed fund The COSF Fund for Advancement in Wellness will ensure that critical support services are available in perpetuity, minimizing the impact of fiscal fluctuations with the COSF endowed fund for Center for Cancer and Blood Disorders at Children’s Hospital Colorado.
