Naples Children Foundation

Grant Guidelines:

The Naples Children Foundation (NCF) was established in 2000 to transform the lives of vulnerable children in Collier County by investing in, and partnering with, proven programs that bridge gaps in education, health care and child advocacy to deliver measurable results.

In 2005, we commissioned The Study of Child Wellbeing, an assessment of the needs of children in Collier County that found significant shortfalls in basic services including pediatric oral health, early childhood education, child advocacy, pediatric medical services and out-of-school services. In 2010, a follow up study was conducted identifying additional voids including childhood hunger, which is now a key area of focus. Further studies conducted in 2017 and 2022 confirmed the persistent need for targeted initiatives to bridge these gaps. These studies led to the development of — and reinforce — the following seven NCF Strategic Initiatives, each designed to address specific areas of need:

• Healthcare and Oral Health (est. 2006)
• Early Learning (est. 2008)
• Hunger (est. 2011)
• Mental Health, Vision and Out-of-School (est. 2012)

Every dollar we generate fuels high-impact solutions and, since its inception, NCF has transformed entire communities and positively impacted the lives of 385,000 children through its strategic investments in close to 90 nonprofit organizations. Every organization considered for funding undergoes a rigorous vetting process to ensure alignment with our mission and efficient use of resources. Post-award, every outcome is tracked to ensure measurable and lasting benefits for the children of Collier County.
