Statewide Inmate Family Council Message:

Local Inmate Family Councils (IFC's) are a gathering of family and friends of the incarcerated who meet regularly with Wardens to support visiting since keeping strong family connections with loved ones is a powerful rehabilitative tool. These IFC's promote visiting by clarifying rules and regulations as well as discussing health, education, vocational training, packages, books, and related issues. For more information on connecting with a local IFC, please visit the Statewide IFC website.
