Our Crisis Diversion Services

Structured behavioral health programs help adults move from acute distress toward stabilization, treatment engagement, and continued recovery.

Crisis Stabilization

Crisis Stabilization & Intervention provides acute support, clinical assessment, risk assessment, safety planning, psychiatric stabilization, and family sessions for adults experiencing a mental health crisis.

Partial Hospitalization

Partial Hospitalization offers intensive outpatient care for adults with mental health, trauma, substance use, and co-occurring disorders through individualized evidence-based treatment.

Intensive Outpatient

Intensive Outpatient treatment provides structured mental health and substance abuse care at a lower level than residential or partial hospitalization programs, with therapies tailored to individual needs.

Compassionate Crisis Care

Support Through Crisis and Recovery

Alter Behavioral Health connects adults experiencing acute psychiatric distress with appropriate support across a full continuum of care. Crisis stabilization includes clinical assessment, risk assessment, safety planning, psychiatric stabilization, and family sessions. When appropriate, clients may transition into partial hospitalization or intensive outpatient treatment, helping address mental health, trauma, addiction, and co-occurring concerns through personalized, evidence-based care across Southern California.

Frequently Asked Questions

What qualifies as a mental health crisis?

A mental health crisis may involve acute emotional or psychiatric distress that makes it difficult to remain safe, function normally, or manage symptoms without immediate support. Examples can include severe mood symptoms, psychosis, overwhelming trauma responses, suicidal thoughts, significant behavioral changes, or substance-related concerns. A clinical assessment helps determine whether crisis stabilization, emergency care, or another level of treatment is appropriate.
