CASA Jefferson was initiated in 1986 under the judicial administration of Juvenile Court Judges.

In 1989, the organization hired the first program coordinator and began a recruitment campaign. Additional growth came about in 2001 under the judicial administration of Scott Griffith and en banc decision of Judges Nancy Amato Konrad, Ann Murry Keller and Andrea Price Janzen. With CVA-VOCA (Crime Victim's Assistance/Victims of Crime Act) and TANF (Temporary Aid to Needy Families), the program expanded to nine employees and more than 70 advocates. Staff and volunteers work diligently to find assistance for each child in the system.
