Working Together for Healthy Schools.

Healthy Schools Don’t Just Happen…
They Need You.

Welcome to CASLE’s website

Children are uniquely vulnerable to toxins and hazards in their environments. Our schools, their condition and the products and practices used in them, can influence children’s health, well being and educational outcomes.

We love our children more than anything, and they are our country’s greatest resource.

Whether you are a concerned parent or teacher, a professional designing a new school, a principal or a maintenance manager, CASLE offers two decades of experience and resources to help solve problems, and to show how healthy school environments benefit students and staff.

Our Mission

With solid information, respect, and persistence as our primary tools we can help provide environmentally healthy products and practices in schools, and healthy school buildings.
