National CASA is Transforming Lives. Nearly 700,000 children experience abuse or neglect each year. Instead of playing with neighbors and making happy family memories, theyâre attending court hearings, adjusting to new foster homes and transitioning to new schools. Thatâs a heavy burden for a child to carry. With a Court Appointed Special Advocate (CASA) or guardian ad litem (GAL) volunteer dedicated to their case, Americaâs most vulnerable children will have someone speaking up for their best interests. With your support, more children will have the opportunity to thrive in a safe and loving home.
