Partial hospitalization provides intensive outpatient care for mental health, trauma, and substance use disorders, using therapies such as CBT, DBT, EMDR, and family therapy.
Intensive outpatient treatment provides structured care at a lower level than residential or partial hospitalization, supporting continued therapy for mental health and substance use concerns.

Alter Behavioral Health combines evidence-based therapies, holistic supports, family participation, and aftercare resources to address mental health, addiction, trauma, and co-occurring disorders.
