Mental Health Programs in Orange County
Find Your Still Water
Stillwater Behavioral Health offers three levels of outpatient mental health care, all from our Costa Mesa location, serving clients throughout Orange County. Rather than locking you into a single track, we build a plan around your clinical needs — and adjust it as those needs change.
Finding the Right Level of Care
Not everyone needs the same intensity of treatment. Some need daily structure to stabilize. Others need a program that flexes around a job or school schedule. Some are stepping down from a higher level of care and just need consistent support to maintain progress. The chart below is a starting point — your actual recommendation comes from a clinical assessment during intake.

Partial Hospitalization Program (PHP)
Our most intensive outpatient option. PHP provides structured, multi-hour daily programming for clients who need more support than weekly therapy but don't require inpatient hospitalization. It's often the right fit if you're stepping down from inpatient care, or if your symptoms have stopped responding to less intensive treatment — for when the turbulence is loudest and daily structure matters most.
Intensive Outpatient Program (IOP)
IOP meets several days a week for a few hours per session, giving clients meaningful clinical support while still working, attending school, or managing family responsibilities. It's a strong fit for clients stepping down from PHP, or anyone who needs more structure than weekly therapy but doesn't require daily programming.
Outpatient Program
Ongoing individual and group therapy — ideal as a step-down after PHP or IOP, or as a standalone option for clients with lower-acuity needs. It's built for maintenance and relapse prevention: enough support to keep your footing, without the time commitment of a more intensive program.
