Outpatient drug rehab in Thousand Oaks lets you recover while living at home and keeping your job, across three levels of care: PHP, IOP, and OP, stepping down as you stabilize. We accept most major insurance, including Aetna, Blue Shield of California, Kaiser, and UnitedHealthcare, and we verify your benefits quickly.
Who our addiction treatment in Thousand Oaks is for
Our addiction treatment in Thousand Oaks is the right level of care when you need structured support but do not require 24-hour residential supervision. Most people who do well in our Thousand Oaks programs are stepping down from detox or a residential stay, working a job they cannot step away from, or dealing with a drug problem early enough that a stable home supports recovery.
This program treats adults 18 and over. We treat addiction to fentanyl and other opioids, heroin, prescription painkillers, cocaine and other stimulants, methamphetamine, and benzodiazepines. Co-occurring depression, anxiety, trauma, PTSD, and bipolar disorder are treated at the same time as the substance use, on a separate dual diagnosis track when that fits you better. We also run a dedicated program for veterans and active-duty military.
What drug treatment in Thousand Oaks looks like
Substance use disorder treatment starts with a clinical assessment by a licensed therapist, often the same day you call, which sets your starting level of care and your schedule. If you need medically supervised detox first, we coordinate it before outpatient treatment begins.
Our outpatient rehab runs three levels of care under one roof in Thousand Oaks, and you move down through them as you stabilize. The difference between them is time in treatment, not the quality of care: every level uses the same clinical team and the same evidence-based methods.
| Level | Days per week | Session length | Who it fits |
|---|---|---|---|
| PHP (Partial Hospitalization) | 5 (Mon-Fri) | Full days | Most structured outpatient level; step-down from detox or residential |
| IOP (Intensive Outpatient) | 5 | 3 hours (morning or afternoon) | Working or family-stable clients who still need real structure |
| OP (Outpatient) | Up to 3 | Includes evening sessions | Relapse prevention and maintenance; fits a weekday job |
A typical week combines one-on-one therapy with a licensed clinician, group therapy, and a family session. Sessions run in person at our Thousand Oaks office or by telehealth, whichever fits your schedule. How long you stay in care is set by clinical progress rather than a fixed calendar.
Therapies and modalities we use
Our substance use disorder treatment uses cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), EMDR, group and family therapy, and medication-assisted treatment across its clinical hours.
CBT is the backbone of the program. It helps you identify the thoughts and situations that drive use and build skills you practice between sessions. DBT is added for clients who struggle with emotional regulation or impulsivity. EMDR is offered to clients carrying trauma or PTSD alongside addiction. For opioid use disorder, medication-assisted treatment pairs FDA-approved medications, Suboxone (buprenorphine) and Vivitrol (naltrexone), with counseling rather than running on its own. We also offer psychiatry, TMS for treatment-resistant depression, and mind-body therapies such as meditation and art therapy.
Outpatient vs. residential drug rehab
Our outpatient programs fit most people with a stable home and work or family they cannot step away from. Residential makes sense when home is unsafe or withdrawal needs 24-hour medical supervision. The practical difference comes down to where you sleep and how much time treatment takes.
| Outpatient (what we offer) | Residential / inpatient | |
|---|---|---|
| Where you sleep | Home or sober living | At the facility |
| Work, school, family | Keep them | Paused |
| Time in treatment | A few hours to full days, by level | Around the clock |
| Right when | Home is stable, you cannot step away | Home is unsafe or detox needs 24/7 care |
If you are not sure which you need, call (805) 856-6690 and a clinician will tell you, including a referral out when residential is the safer option.
Drugs we treat
We treat addiction to opioids, stimulants, and benzodiazepines at the outpatient level, including:
- Fentanyl and other opioids
- Heroin
- Prescription painkillers such as oxycodone and hydrocodone
- Cocaine and other stimulants
- Methamphetamine
- Benzodiazepines such as Xanax, Klonopin, and Ativan
- Alcohol
Insurance
We work with most major insurers on both an in-network and out-of-network basis, including Aetna, Blue Shield of California, UnitedHealthcare, Kaiser Permanente, Optum, Anthem Blue Cross, BCBS, GEHA, and UMR, and we verify your benefits on any plan quickly.
Most commercial insurance covers outpatient care with prior authorization, and under federal law, plans that cover substance use treatment can't limit it more strictly than other medical care. Rather than guess at what your plan includes, we verify your benefits for you and explain what is covered before you start.

"This is the first program I've been to that has a separate mental health and substance track, and because of that actually acknowledges the individuals who are not addicted just as much as the people who are addicts in recovery. Everyone's voice was heard and everyone mattered."Sierra E., former client
"My treatment experience here was excellent and I am grateful for everything they did for me. The entire staff was awesome and finally I am headed in the right direction in life after leaving."Chris W., former client
Frequently asked questions
How much is a week of rehab?
With insurance, most clients pay only their deductible and coinsurance, not the full sticker price. A week of outpatient care in Thousand Oaks costs far less than residential care because there is no room-and-board charge. Call (805) 856-6690 for a figure based on your plan.
What is the average stay in drug rehab?
Outpatient drug addiction treatment runs several weeks to a few months for most clients, moving from PHP to IOP to OP as you stabilize. Your length is set by clinical progress, not a fixed number of days.
Do you have to pay to go to rehab for drugs?
Most people pay only their plan's share, not the full price. We accept carriers including Aetna, Blue Shield of California, and Kaiser, and most commercial plans cover outpatient care with prior authorization. We verify your benefits quickly.
What's the longest you can stay in rehab?
There is no fixed cap on outpatient care. Many clients stay in a step-down OP track for several months for relapse prevention, and insurance continues coverage through continued-stay reviews based on medical necessity. We keep you at the level you need for as long as it is clinically justified.
Can I keep working during drug rehab?
Yes. Our IOP runs five days a week for three hours a day in the morning or afternoon, and our outpatient program includes evening sessions, both built around work and family schedules, with in-person and telehealth options. You attend sessions and return home the same day.
Do I need medical detox before outpatient care?
Sometimes. If you are physically dependent on opioids or benzodiazepines, we coordinate medically supervised detox first, then move you into PHP or IOP. Your intake assessment determines whether detox is needed before outpatient treatment begins.
Do you offer Suboxone treatment in Thousand Oaks?
Yes. For opioid use disorder, our medical team offers Suboxone (buprenorphine) and Vivitrol (naltrexone) paired with counseling and therapy. We do not offer methadone. Our Medical Director decides with you whether medication fits your treatment plan.
