A Court Appointed Special Advocates program, CASA of San Mateo County’s mission is to ensure that all abused and neglected children under the protection of the court have a consistent, caring adult to help them reach their full potential.

The more healthy relationships a child has, the more likely he will be able to recover from trauma and thrive. Relationships are the agents of change and the most powerful therapy is human love...People, not programs, change people.
— Dr. Bruce Perry

 CASA of San Mateo County pairs foster children with community volunteers who provide one-on-one support, mentoring and advocacy in the courtroom and beyond. You could be one of our caring, dedicated CASA Volunteers who help children heal from trauma and access the services they need to thrive. Join a national network of more than 76,000 volunteers standing up for the rights of abused and neglected children in their community.
