The Westchester County Department of Social Services (DSS) assigns all newly homeless families in the County to the Westhab Family Assessment Center, in Elmsford. Families live there for about two weeks, while a multi-disciplinary team, including a psychologist, physician, public health nurse, social worker, and certified substance abuse counselor conduct a series of interviews and examinations to determine the root causes of their homelessness and the most appropriate housing placement. This team makes a written recommendation to DSS' Central Placement Unit (CPU), which maintains a database of all homeless housing resources in the County. The CPU then assigns each newly homeless family to a vacant unit based on Westhab's Family Assessment Center's recommendation.
