Crisis Stabilization

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

Residential Treatment

Residential treatment offers structured, person-centered care for adults needing comprehensive support for mental health, trauma, PTSD, psychiatric disorders, or co-occurring drug and alcohol addiction.

Partial Hospitalization

The Partial Hospitalization Program provides intensive outpatient care using evidence-based approaches such as CBT, DBT, EMDR, and family therapy for mental health, trauma, and substance use disorders.

Compassionate Crisis Care

Support Beyond the Emergency Room

An emergency room can address immediate medical safety, but ongoing behavioral health needs may require a more specialized plan. Alter Behavioral Health connects adults with crisis stabilization, residential, partial hospitalization, and intensive outpatient services across Southern California. Care may include assessment, safety planning, psychiatric stabilization, evidence-based therapies, family participation, and aftercare planning tailored to each person’s needs.

Frequently Asked Questions

What qualifies as a mental health emergency?

A mental health emergency may involve an immediate concern about someone’s safety, severe psychiatric symptoms, an acute emotional crisis, or a situation requiring urgent clinical assessment. If someone may harm themselves or another person, has a serious medical concern, or cannot remain safe, call 911 or go to the nearest emergency room. Crisis support can help determine appropriate next steps when safety is uncertain.
