Outpatient Mental Health Program in Costa Mesa
Our outpatient program provides ongoing individual and group therapy for clients in Costa Mesa and throughout Orange County — steady support for calmer waters that still need tending. It's frequently used as step-down care after PHP or IOP, and it's also available as a standalone option for clients whose needs don't require a more intensive level of care.
What Is Outpatient Mental Health Treatment?
Outpatient treatment is the least intensive level of structured mental health care we offer — typically weekly or biweekly sessions rather than multiple visits per week. It's designed for clients who are relatively stable but benefit from ongoing clinical support, accountability, and skill reinforcement.

Who Outpatient Therapy Is For
Outpatient care may be the right fit if you:
- Have completed PHP or IOP and want to maintain progress with less frequent sessions
- Are managing a condition that responds well to regular weekly or biweekly therapy
- Want ongoing support for stress, grief, life transitions, or maintenance of previously treated conditions
- Prefer a lower-commitment option than IOP or PHP
- Need continuity of care with a provider who understands your full treatment history
What to Expect in Outpatient Therapy
Sessions are typically one-on-one, though group therapy options may also be available depending on clinical recommendation. Treatment continues to draw on evidence-based approaches like CBT and DBT, adjusted to a lower-frequency format.
Where Treatment Takes Place
Outpatient sessions are held at our Costa Mesa facility, serving clients throughout Orange County.
Outpatient as Step-Down Care
