Help create equal access to quality summer programming

​Because summer matters!
DONATE NOW

Donate now to our Summer Matters Campaign!

Summer Matters is a bold $1.5 million campaign to ensure every child, regardless of income, zip code, or circumstance, has access to high-quality, life-changing summer learning opportunities.

Summer is a pivotal time for children and communities alike. When young people have access to enriching summer programs, they build academic skills, gain confidence, explore STEM, develop meaningful relationships, and return to school better prepared to succeed. 

Talent is universal. Opportunity is not. That's why Summer Matters is expanding access to inclusive, high-quality summer programming so every child has the chance to learn, grow, and thrive. 
Because every child deserves a summer that matters
