Learn more about how you can advocate for a child in foster care as a CASA volunteer and make a difference for generations to come! Sign up for one of our upcoming Info Sessions: CASA volunteers advocate one-one-one for abused and neglected children in the foster care system. They are commited to making a difference for children who might otherwise slip through the cracks of an overburdened foster care system or languish in an inapropriate placement. CASA volunteers are appointed by a juvenile court judge to help ensure that every child in foster care is moved to a safe permanent home. You must be 21 years or older to volunteer.
