CASA of Northeast TN had its beginnings at East Tennessee State University when in 1985, at the initiative of the Sociology Department, funds were obtained through a one-time grant from the U.S. Department of Health and Human Services to establish the organization. In 2004, CASA of Northeast TN moved out from under the umbrella of ETSU and became established as a 501(c) 3 entity. CASA of Northeast TN now serves over 250 children a year in 4 juvenile courts: Washington County, Johnson City, Greene County, and Unicoi County. CASA of Northeast TN has won hard gains by increasing full-time staffing to 5 (Executive Director, 3 Program Coordinators, and Volunteer Coordinator) and over 35 volunteer advocates.
CASA of Northeast Tennessee is a member in good standing with the National CASA/GAL Association for Children and the Tennessee CASA Association.
