Upcoming Events
Children’s Oncology Support Fund is thrilled to return to Aspen for the 4th Annual Aspen Snow Ball — our signature black-tie gala at the heart of a multi-day celebration of community, compassion, and commitment to a brighter future for children battling cancer.
Aspen Snow Ball Week is more than just a social gathering — it’s a powerful convergence of purpose and philanthropy. Over the course of three unforgettable days, influential supporters, brands, and celebrated entertainers come together to stand united in the fight to end pediatric cancer.
This year’s gala will feature exclusive performances, community-driven moments, and a spotlight on extraordinary individuals whose humanitarian and philanthropic efforts reflect the heart of our mission. Whether you’re joining us in Aspen or supporting from afar, your presence helps fuel vital programs in music and art therapy, holistic healing, critical care, life programming and innovative pediatric cancer research.
Join us for a weekend of impact, and inspiration — because every voice, every gift, and every shared vision brings us one step closer to a cancer-free future for children everywhere.
