The Children’s Oncology Support Fund (COSF) hosted its highly anticipated 4th Annual Aspen Snow Ball Gala at the St. Regis Aspen on the evening of March 21st, bringing together leaders in philanthropy, entertainment, and business for an unforgettable evening dedicated to advancing pediatric cancer research and wellness programs nationwide.
This year’s elegant black-tie affair embraced a purple and gold palette inspired by the “Pure Imagination” theme, creating an immersive environment filled with magic, wonder, and possibility. The evening underscored a powerful message at the heart of COSF’s mission: remission is the goal—the golden ticket.
The gala supports COSF’s ongoing efforts to fund the development of less toxic therapies for children battling cancer across the United States. Through grants and pledged funding, COSF advances critical patient programs while working directly with hospitals and nonprofit partners to expand access to care.
The evening was led by COSF Founder, Aspen Snow Ball Chairman, and film producer Thomas Pierce, with Chelsea Handler serving as host. Notable honorees included Philanthropic Achievement Honoree Goldie Hawn, recognized for her work with the MindUP program through The Goldie Hawn Foundation, and Humanitarian of Light Award Honoree Stella Roy. Hawn attended alongside Kurt Russell and was presented her award by Dr. Lawrence Piro, following a heartfelt video tribute and remarks from Kate Hudson.
Guests were treated to standout performances by Wilson Phillips, Rumer Willis, and Mojave Grey, with Wilson Phillips delivering the evening’s headlining set. The program opened with a theatrical presentation inspired by Charlie and the Chocolate Factory, featuring Christian Madsen as Grandpa Joe, Mariah Claire Mothner as Charlie, and narration by William H. Macy.
From live and silent auctions to a spirited balloon pop experience, the evening delivered a dynamic and emotionally resonant program filled with generosity, hope, and purpose.
“Being honored at the Aspen Snow Ball fills my heart with gratitude,” said Goldie Hawn. “What inspires me most is the unstoppable spirit of the children and families COSF serves. To be part of a community that lifts them up, celebrates their courage, and expands holistic care is one of the greatest joys of my life.”
