The continuum of care, defined

Each level above simple weekly therapy provides a fundamentally different clinical environment. For referring providers weighing where a teen belongs, the distinction is not severity, it is the structure and containment that surround the therapy hour.

Intensive Outpatient Programming (IOP)

1–3 hours/day · Weekly therapy
Muir Wood provides this level

Provides
- Individual & group therapy
- Medication management (sometimes)
- Skill building & psychoeducation
- Family check-ins
Key limitations
- Teen returns to the same home environment daily
- No 24/7 clinical monitoring
- Crisis support is reactive, not proactive
Partial Hospitalization (PHP)

5–6 hours/day · Nights at home
Not operated by Muir Wood

Provides
- Intensive daily programming
- Psychiatric oversight
- Group & individual therapy
- Structured peer environment
Key limitations
- No overnight containment or safety monitoring
- Teen returns home each evening; triggers remain
- Not equipped for active safety risk
The only level where the environment is part of treatment

Residential (RTC)

24/7 · Immersive therapeutic community
Muir Wood provides this level

Provides
- Round-the-clock clinical support & safety
- Complete therapeutic environment
- Daily individual, group & family therapy
- Milieu as medicine: 24/7 therapeutic community
- Removal from destabilizing home and social environments

The only level where the environment itself is part of treatment, 24 hours a day.

When the clinical picture points to residential

Safety concerns that require containment

Active or recent self-harm, suicidal ideation with intent or plan, or inability to maintain safety agreements. PHP cannot provide overnight monitoring; these teens need 24/7 clinical presence.

ASAM Dim. 3 · Emotional/Behavioral/Cognitive CALOCUS Risk of Harm
Chronic emotional dysregulation across settings

Dysregulation that is not confined to one relationship or context. When a teen cannot regulate at school, home, and with peers, the environment itself needs to change, not just the therapy frequency.

ASAM Dim. 3 · Emotional/Behavioral/Cognitive CALOCUS Functional Status
The home environment is a clinical risk factor

Family conflict, trauma originating in the home, parental mental illness, or dynamics that actively destabilize the teen. Returning home each evening re-exposes the teen to what is driving the crisis.

ASAM Dim. 6 · Recovery Environment CALOCUS Recovery Environment
PHP or IOP has already failed to hold

A teen who has been through outpatient, IOP, or PHP without sustained improvement is a residential candidate. Prior treatment failure is a clinical indicator, not a barrier.

ASAM Dim. 5 · Relapse/Continued Problem Potential CALOCUS Resiliency & Treatment History
Inability to engage in lower-level care

Teens who cannot attend, participate in, or benefit from structured day programming due to symptom severity. If engagement collapses when structure ends each day, residential structure is what is needed.

ASAM Dim. 4 · Readiness to Change CALOCUS Acceptance & Engagement
Complex co-occurring presentations requiring 24/7 integration

When psychiatric, trauma, and behavioral dimensions need to be held simultaneously, not just during programming hours, residential is the environment that can actually do that.

ASAM Dim. 2 + Dim. 3 · Biomedical & Emotional/Behavioral CALOCUS Co-Morbidity

These align with the dimensional admission criteria used by ASAM and CALOCUS, the frameworks clinicians and insurers use to evaluate medical necessity and authorize residential placement.

Where Muir Wood Fits on the Continuum

Muir Wood provides residential (RTC) and intensive outpatient (IOP) care for teens ages 12 to 17, along with aftercare and alumni support. When a teen needs a level we do not provide — inpatient stabilization, partial hospitalization, or routine outpatient therapy — our team helps the family identify the right setting and coordinates the referral.

Residential. Our residential program fits teens who have not achieved sustained progress in outpatient, IOP, or PHP, but who do not need inpatient hospitalization. A typical stay is 45 to 60 days, up to 90 when clinically indicated, with individual, group, and family therapy on hub-and-spoke campuses in Sonoma, Riverside, and Fresno Counties.

Intensive outpatient. Our IOP is a fixed 12-week program that meets three to four days a week after school, with group therapy, individual therapy, family therapy, optional 12-step support, parent education, and care coordination, at our Petaluma IOP and Fresno IOP Center.

Aftercare. Recovery continues after discharge through our alumni and aftercare support, including a 16-week aftercare coaching program.

How Placement Actually Works

Placement isn’t always linear

A teen doesn’t have to start at the top and work down — a clinician might place someone directly into IOP or residential based on clinical need, even if they have never been in a higher level of care.

Step-downs can go back up

If a teen struggles after stepping down — a crisis at home, a relapse, or school refusal — they can step back up to a higher level of care temporarily. The goal is always the least restrictive level that meets clinical need.

Family involvement grows as intensity decreases

In a residential setting, family therapy is scheduled and contained; by IOP and outpatient, families are doing much more of the real-time support work — which is why family therapy and parent coaching become especially important at those levels.
