Welcome 

We're a volunteer-run parent, teacher, and student organization dedicated to strengthening the partnership between families and school staff of Costa Mesa Middle School and High School.

Our mission: advocate for every child, support our teachers and campus programs, and build a connected school community through volunteer events, fundraising, and family engagement throughout the year.

The PTSA brings together parents, guardians, teachers, staff, and students who care about our school. We work to strengthen communication between home and school, staff classrooms and campus programs with volunteers, raise funds for student and staff needs, and create everyday ways for families to get involved.

Joining is easy. Membership is just $11, and meetings are 100% optional — join to support the school, get involved as much or as little as you'd like.
