Guided by a board composed primarily of grassroots leaders, Community Toolbox seeks to build the organizational capacity and sustainability of parent and other community-based organizations working to eliminate children's environmental health threats, such as lead poisoning, in communities at highest risk. Community Toolbox addresses the needs of environmental health and justice groups serving children in disproportionately impacted communities through grantmaking, technical assistance, and community building programs, all of which aim to locate control on the grassroots level.
