Crisis Stabilization Unit...

  • Provides psychiatric assessments, referrals, recommendations and consultation on behalf of individuals who arrive on an involuntary basis (Pursuant: California Welfare and Institutions Code 5150), and for those who come to CSU voluntarily. Typically clients are experiencing a mental or emotional crisis; in that they may be deemed a danger to themselves or to others, or they may appear incapable of caring for their basic needs.
  • Provides crisis stabilization; i.e., individualized interventions directed toward resolution of the presenting, psychiatric episode.
  • Provides evaluations of clients for whom inpatient psychiatric hospitalization appears indicated. Admissions for inpatient, psychiatric hospitalization are arranged as necessary.
  • Some clients may be referred to Bay Area Community Resources (BACR) or to work with Community Action Marin through the use of a Family Partner to address drug and/or alcohol use issues.  
  • The role of the Family Partner is to support the family (through the crisis) as an advocate and link them to community resources
  • Provides referrals to other county and community-based agencies and services

Referrals to CSU are received from families and individuals, from all County of Marin departments, our thirteen, local law enforcement agencies, community health providers and agencies, and from facilities and agencies throughout Northern California.
