    Help Us Find a Cure.

    We've made incredible progress in the fight against cystic fibrosis, but we still have a long way to go.

    Far too many lives are being cut short by this devastating disease.

        2023 National Ambassadors

        Lauren Luteran National Ambassador for CFF

        Cru Aguinaga

        Cru Aguinaga was diagnosed with cystic fibrosis at 5 weeks old. He loves animals, playing with his siblings, Adair and Witten Rose, and eating — namely noodles, brownies, and strawberries. Cru’s support system consists of his brother and sister, his dog, Nala, his mom and dad, and all his friends and family. As a 2023 national ambassador for the Cystic Fibrosis Foundation, he looks forward to showing what CF means to him and his family.

        Saiul Merrero National Ambassador for CF

        Elle Kellner

        Elizabeth (Elle) Kellner was diagnosed with cystic fibrosis at 4.5 months old and is a double-lung and kidney transplant recipient. As a child, she remembers being told she couldn’t do some of the things her peers did because she wasn’t “strong enough” or she was too sick. However, she is not one to give up easily and never accepts no as an answer. In her free time, she loves yoga, cooking, dancing, and going to the beach. In 2007, following a toy drive she ran alongside her husband, she started a non-profit that benefits pediatric patients at her local hospital.
