Our PHP Housing Services

Structured behavioral health programs supporting adults through partial hospitalization, residential care, outpatient treatment, and crisis stabilization.

Partial Hospitalization

PHP provides intensive outpatient mental health care for adults with conditions including depression, anxiety, bipolar disorder, trauma, PTSD, schizophrenia, borderline personality disorder, and substance use disorders.

Residential Treatment

Residential mental health treatment offers a more immersive setting for adults needing comprehensive care, person-centered support, family participation, and evidence-based treatment for complex psychiatric or co-occurring disorders.

Intensive Outpatient

IOP provides structured mental health and substance use treatment at a lower level of care than PHP or residential treatment, helping clients continue progress while practicing skills in everyday life.

Personalized Clinical Support

Supportive Housing for Continued Healing

PHP housing can provide adults with a stable, supportive setting while they participate in intensive outpatient treatment. Alter Behavioral Health combines individualized care plans with CBT, DBT, EMDR, family therapy, and other therapeutic approaches. Across Southern California locations, clients can work on symptom management, coping skills, recovery goals, and a gradual transition toward daily life with coordinated clinical support.

Frequently Asked Questions

What is the difference between PHP and residential?

Partial Hospitalization Program care is an intensive outpatient level of treatment, while residential treatment provides a more immersive living environment with comprehensive support. PHP may be appropriate for adults who need structured clinical care but do not require residential services. Residential treatment may better fit people needing greater supervision, daily support, or a more contained setting. An assessment helps determine the appropriate level of care.
