Crisis Stabilization Unit (CSU) This 8-bed facility provides a short-term stay (up to 5 days) for individuals needing additional stabilization services following a behavioral health crisis. Guests must consent to receive services because the CSU is a voluntary facility. The CSU provides step-down services for individuals discharging from psychiatric facilities who need additional support prior to returning home. While at the CSU, guests receive individual counseling, a complete mental health assessment, case management services and connection to local resources. The Crisis Stabilization Unit is at 403 Municipal Drive, Carterville, Ill. For a pre-admission assessment, please click here.
