The Pied Piper Foundation began in 2020, when Ava Johnson, with the support of her parents, Mat and Ana, created a foundation following her diagnosis with ependymoma.
Since then, the Johnson family has built a commitment to pediatric brain tumor research that extends well beyond any single study. With a particular focus on ependymoma and other rare tumors, Pied Piper invests in the long-term research, infrastructure, and collaboration needed to move promising science toward better treatments for children.
That philosophy has led Pied Piper to the Executive Council of the Children's Brain Tumor Network, where the foundation supports preclinical research and data infrastructure designed to make future clinical trials more precise and impactful.
It is also what makes Pied Piper such an important partner to PNOC. Mat and Ana have consistently trusted PNOC to direct their support where it can have the greatest impact, helping strengthen the research and infrastructure behind our clinical trials. Year after year, they have also supported the PNOC Foundation Gratitude Gala, helping bring together the families, researchers, physicians, and partners who make this work possible.
We are incredibly grateful to Ava, Mat, Ana, and the Pied Piper Foundation for their trust in PNOC and for investing not only in today's research, but in the foundation required to make tomorrow's discoveries possible.
