Our Crisis Stabilization Unit Services

Immediate behavioral health support focused on assessment, stabilization, safety, and coordinated next steps for adults experiencing crisis.

Clinical Assessment

Professionals evaluate immediate mental health needs, risks, symptoms, and clinical concerns to inform an individualized stabilization plan for the person in crisis.

Psychiatric Stabilization

Acute care support addresses urgent psychiatric needs through clinical oversight and evidence-based approaches designed to help individuals regain stability during a mental health crisis.

Safety Planning

Care includes risk assessment and collaborative safety planning to identify immediate supports, practical precautions, and appropriate next steps after stabilization.

Family Sessions

Family participation can help loved ones understand the crisis, support communication, and contribute to a coordinated plan for continued behavioral health treatment.

Dual Diagnosis Support

The CSU can support adults experiencing mental health concerns alongside substance use issues, helping connect crisis intervention with broader dual-diagnosis care.

Continuum Coordination

Crisis stabilization is part of Alter’s broader care model, creating opportunities to consider residential, PHP, IOP, or other ongoing treatment after immediate needs are addressed.

Frequently Asked Questions

How long does someone stay in a crisis center?

The length of stay in a crisis stabilization setting varies according to the individual’s clinical needs, safety concerns, response to intervention, and recommended next level of care. The purpose is to address immediate crisis needs and support stabilization, not to provide a fixed long-term treatment period. During care, clinicians evaluate progress and help plan appropriate ongoing support.
