Teen intensive outpatient treatment in Petaluma
Teen struggles with mental health, trauma, or substance use can be challenging. They may be falling behind at school, struggling with mood swings, or distancing from family. Our Adolescent Intensive Outpatient Program (IOP) in Petaluma supports teen mental health for ages 12–17 without removing them from home or school.
Over 3–4 days a week, teens engage in evidence-based therapy, including individual sessions, group therapy, and family support, to build coping skills, strengthen communication, and restore routines. Teens receive thoughtful support for mental health issues, substance use, and co-occurring challenges. Think of it as a right-sized structure — more supportive than traditional outpatient therapy, yet flexible enough to complement ongoing care without the intensive, 24/7 structure of residential treatment.
If you’re unsure whether IOP or a higher level of care is the right fit for your teen, our team will guide you with personalized advice to determine the safest and most effective path forward for your loved one.
Weekly schedule and length of the Petaluma teen IOP
Our Petaluma IOP combines clinical expertise with hands-on skill-building, helping teens apply what they learn in real time. Each teen develops a personalized treatment plan crafted by licensed mental health professionals and progresses through evidence-based therapies and structured skills practice tailored to adolescent needs. Sessions take place in person after school, allowing teens to stay engaged with home and academics. The program also serves as a step-down from residential care when a lower level of support is clinically appropriate.
Programming, offered 3–4 afternoons per week, includes:
- 9 hours of group therapy (3 sessions per week)
- Weekly individual therapy
- Family therapy every 1–2 weeks
- A weekly virtual parent support group
- Optional introductory 12-step meetings for teens addressing substance use
- Drug testing when clinically indicated
*Some individual and family therapy sessions will take place Tuesday and Friday between 4:00–7:00 PM.
Treatment is typically between 8 and 12 weeks, depending on necessity and insurance coverage. Your teen’s clinical team reviews progress throughout the program and talks with you about timing as you go.
Personalized treatment plans for teen mental health and substance use
We individualize care for every teen, creating treatment plans that address the whole person, not just symptoms. Each program integrates support for mental health, substance use, relationships, school performance, and daily routines to ensure progress lasts beyond therapy.

Group therapy in our teen IOP
Our IOP cohorts are intentionally small, creating space for focused attention in therapist-led groups while fostering strong peer connections. Teens build trust and safety within a consistent group, learning from each other’s experiences while developing healthy communication and coping skills. Individual sessions complement group work, supporting continued personal growth.
Types of therapy used in our Petaluma teen IOP
Each teen’s treatment plan is built around their needs and goals. When clinically appropriate, we integrate specialized support for ADHD, trauma-related symptoms, or disordered eating, coordinating closely with outside providers to ensure seamless care.
The result is a focused, flexible program that meets teens where they are and helps them move forward with practical, lasting skills. More detail is available on our treatment therapies page.
Core therapeutic approaches in our IOP include:
Cognitive-Behavioral Therapy (CBT)
Teaches teens how to spot negative thinking patterns, face fears instead of avoiding them, and manage anxiety or depression using real-world tools they can apply every day.
Dialectical Behavior Therapy (DBT)
Builds emotion regulation, distress tolerance, and interpersonal effectiveness — skills teens can practice in groups, at home, and at school.
Acceptance & Commitment Therapy (ACT)
Encourages values-based choices, mindfulness, and meaningful action, even when life feels overwhelming.
Seeking Safety (trauma-informed groups)
Strengthens coping, stability, and safety without requiring trauma exposure.
Relapse prevention for co-occurring substance use
Helps identify triggers, manage cravings, and develop refusal and safety planning skills.
Mindfulness & experiential therapies
Uses guided mindfulness, creative expression, and movement to reduce stress and build self-awareness.
Process & psychoeducation groups
Focuses on problem-solving, communication, and education about mental health, substance use, and healthy daily routines.
Family therapy sessions
Provides coaching and shared sessions for caregivers and teens to strengthen communication, boundaries, and consistency at home.
Family therapy and parent support in our Petaluma IOP
Healing extends beyond the individual — it’s a family process. From your first conversation with our admissions team through aftercare, we involve parents and caregivers every step of the way, so growth in treatment becomes growth at home. Families participate in regular therapy sessions and receive consistent, compassionate updates, along with hands-on coaching in communication, boundaries, and routines that foster trust and reduce conflict. Virtual options make it easier to stay engaged, even on busy days.
Support continues long after discharge. Our team helps plan next steps, coordinates with outside providers (with your consent), and offers ongoing education through our 16-week parent aftercare coaching program. Teens remain connected through alumni touchpoints and community events. Together, these connections give families the insight, tools, and confidence to sustain long-term progress and healing.
Our approach is described in more detail on our family programming page.
How teen IOP compares to residential treatment
Levels of care
Not sure which level of care fits your teen?
Support for teens ranges from weekly therapy to around-the-clock residential care. See how the levels compare and which one fits where your teen is right now.
Not sure which level of care fits your teen? Our guide to levels of care walks through each one side by side.
IOP is an after-school level of care. Your teen lives at home, attends school, and comes to treatment 3–4 afternoons a week. It can serve as a step up from weekly outpatient therapy or a step down from residential care.
Residential treatment provides 24/7 care and supervision for teens who cannot remain safe at home or whose needs go beyond scheduled sessions. We operate three residential campuses in Sonoma County: Skillman for boys, Lohrman for girls, and Penngrove for girls receiving primary mental health care. Teens completing residential care often step down to our Petaluma IOP as they return to school and home life.
Meet the Petaluma IOP treatment team
Our clinical team is focused on helping teens develop the insight and skills needed for long-term success. Licensed clinicians and psychiatric providers work closely with families to reinforce progress, clarify expectations, and support transitions between levels of care. This partnership helps ensure gains made in treatment carry forward into daily life at home.
How we coordinate with your teen’s other providers
We believe strong outcomes depend on continuity and collaboration. From admission through discharge, we coordinate closely with your teen’s existing providers and aftercare programs — whether that’s our IOP or another trusted outpatient partner. Our team stays in regular communication with the broader care network to support timely transitions, shared understanding, and a clear path forward.
Therapists, school staff, and case managers looking to refer a teen can find what they need on our page for professionals, or on our continuum of care page.
Aftercare support after teen IOP
Support doesn’t end when treatment does. Muir Wood stays connected with families through coordinated aftercare and ongoing community support.
After completing IOP, families receive:
- Referrals for continued individual or psychiatric care
- Alumni check-ins and virtual teen support groups
- A complimentary 16-week parent aftercare program focused on communication, boundaries, and long-term success
Insurance coverage for the Petaluma teen IOP
Muir Wood is in-network with most commercial insurance. What your plan covers depends on your policy and the level of care, so our admissions team verifies benefits quickly and explains any deductible, co-pay, or co-insurance upfront. We are not in network with Medicaid or Medi-Cal.
Because coverage can affect the approved length of care, we keep those conversations going during the program rather than only at the start.

Petaluma Teen IOP FAQs
What are the benefits of Teen IOP in Petaluma?
Teen IOP provides the right-sized structure to help adolescents (12–17) make progress in mental health and substance use treatment while staying engaged in daily life. Meeting after school 3–4 days a week for about three hours, teens build coping skills, practice them at home and in school, and bring successes and challenges back to group therapy. Families are actively involved through regular family sessions and parent education, supporting safety, stability, and steady growth.
What is an Adolescent Intensive Outpatient Program (IOP)?
An adolescent IOP is a structured, after-school treatment program for teens who need more support than weekly therapy but do not require 24/7 residential care. At Muir Wood Petaluma, teens receive therapist-led group sessions, individual therapy, family sessions, and parent education. This program addresses primary mental health conditions, substance use, and co-occurring disorders in one coordinated plan.
When should my Teen attend a mental health or substance use IOP?
Teen IOP is ideal when a teen can safely remain at home but is not improving with weekly therapy alone. Signs include declining grades, school avoidance, persistent anxiety or depression, mood swings, escalating home conflict, emerging or episodic substance use, and difficulty managing stress or emotions. If a higher level of care is needed, we help coordinate a safe transition.
How do I choose the right Intensive Outpatient Program (IOP) for my teen?
Choose an adolescent-specific program, staffed with licensed clinicians, offers evidence-based therapies (e.g., CBT, DBT), includes family involvement, small group sessions, clear safety protocols, and coordination with schools and other providers. Ask about schedule, wait times, insurance coverage, and aftercare options. We guide families to determine if Petaluma Teen IOP is the right fit.
What payment options are available for a teen IOP?
We’re in-network with most commercial insurance and can verify benefits quickly. Your coordinator will explain any deductible, co-pay, or co-insurance upfront. For out-of-network coverage, we explore single-case agreements and provide documentation for reimbursement, reducing financial stress so families can focus on care.
How is teen IOP different from residential treatment?
Residential treatment provides 24/7 care for teens in crisis. Teen IOP provides structured, clinically intensive care after school, allowing teens to live at home and attend school. Many families use IOP as a step-down from residential care or a step-up from weekly therapy, depending on clinical need.
Can teens without substance use issues be admitted?
Yes. Teen IOP addresses both primary mental health conditions (anxiety, depression, trauma, OCD, ADHD) and substance use (alcohol, cannabis, stimulants, opioids). Integrated care for co-occurring disorders is provided when both needs are present.
Do you treat adolescents with eating disorders?
We do not provide specialty eating disorder programs requiring medical or nutritional supervision (e.g., anorexia, bulimia). We do treat disordered eating when it occurs alongside other mental health concerns and is safe for an IOP setting. During admission, we screen carefully and, if necessary, provide a warm referral to a specialized program.
When your teen needs more than outpatient care
Our Neurodivergent Program at Sonoma Mountain is a specialized residential program for neurodivergent teens assigned male at birth, ages 12 to 17 — for when anxiety, depression, or overwhelm has grown beyond what weekly support can hold. For neurodivergent girls, our Penngrove campus offers specialized mental health residential care.
