Sydney Moss is a junior at Dunwoody High School in Georgia and one of two recipients of the 2025 William R. Simms Award for Outstanding Youth in Philanthropy, presented by the Association of Fundraising Professionals. Born with a rare liver disease, Sydney turned her health journey into a mission—launching Concert for a Cause while awaiting a transplant. Since then, she’s raised over $75,000 for biliary atresia research at Children’s Healthcare of Atlanta and recently established the Sydney Moss Fund. We spoke with her live at AFP ICON in Seattle.
