A full continuum of behavioral health programs supports adults through changing levels of psychiatric and therapeutic care.

Residential Treatment

Residential mental health treatment provides comprehensive inpatient support for adults with complex psychiatric, trauma, and co-occurring needs, with individualized plans and evidence-based therapies.

Crisis Stabilization

Crisis Stabilization and Intervention offers acute care, clinical assessment, safety planning, psychiatric stabilization, and family sessions for adults experiencing a mental health crisis.

Partial Hospitalization

The Partial Hospitalization Program offers intensive outpatient care using CBT, DBT, EMDR, family therapy, and other approaches tailored to individual mental health and trauma-related needs.

Intensive Outpatient

Intensive Outpatient treatment provides structured mental health and substance use support at a lower level of care than residential or partial hospitalization programs.

Trauma-Focused Therapy

Treatment may integrate trauma-focused modalities, including EMDR, alongside CBT, DBT, mindfulness, family participation, and other evidence-based therapeutic approaches.

Dual Diagnosis Care

Dual diagnosis treatment addresses co-occurring mental health and substance use concerns through coordinated care across residential, crisis, PHP, and IOP programs.

Whole-Person Treatment

Personalized Care for Complex Needs

Dissociative disorders can involve complex mental health and trauma-related needs requiring thoughtful assessment and coordinated support. Alter Behavioral Health offers a full continuum of care across Southern California, from crisis stabilization and residential treatment to PHP and IOP.
