Volunteer Opportunities

Project Cornerstone engages with local preschools, elementary schools, and middle schools with parent engagement programs. These programs increase the number of caring adults in schools, parent engagement, and help build caring and welcoming schools. To read more thorough descriptions of these programs visit the School Based Programs page.

Each program includes mandatory training and all volunteers must meet the volunteer policies of their school and school district and YMCA Project Cornerstone. These brief descriptions explain level of commitment for each program.
