Lakeway CASA: Protecting Children in Grainger, Hamblen, Jefferson, and Sevier Counties. WHAT is a CASA VOLUNTEER? Each CASA program or agency professionally trains and carefully screens volunteers to become Court Appointed Special Advocates for abused and neglected children in juvenile court. These volunteers represent the best interests of the victimized child with the goal of securing a safe, permanent home. Tennessee state law allows for judges to appoint CASA volunteers to “speak up” for the child’s best interests. CASA volunteers do not work for the child’s family, the state, or other interested parties. They work for the child. Most CASA volunteers represent only one child, or family of children at a time. CASA is a local, nonprofit organization in communities all across the nation. Since CASA’s national inception, CASA volunteers have helped more than two million children find safe, permanent homes. Lakeway CASA’s Mission, Vision, and Value Statement: The Mission of Lakeway CASA is to provide trained community volunteers to advocate for the best interest of abused and neglected children. The goal of our advocacy is to help find each child a safe, loving and permanent home. Our Vision is to provide a highly trained volunteer Advocate for every abused and neglected child in Grainger, Hamblen, Jefferson and Sevier County court systems.
