CASA - Court Appointed Special Advocates for Children. Serving children in Cleveland, McClain and Garvin Counties. The mission of South Central CASA of Oklahoma, Inc. is to recruit, screen, train, and supervise volunteers to advocate for the best interests of children who have been abused or neglected. When a child becomes the subject of a deprived proceeding under Title 10A of the Oklahoma Children's Code, a Court Appointed Special Advocate (CASA) may be appointed at the request of a party or based on the judge's determination that the child would benefit from advocacy by a third-party. It is the goal of South Central CASA to provide a trained volunteer for every child involved in a deprived proceeding in Cleveland, Garvin, and McClain Counties.
