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
