Outpatient Mental Health Treatment in Thousand Oaks & Westlake Village, CA

You don’t need to be struggling with addiction to need support. Lotus Recovery offers a dedicated primary mental health track, separate from our substance use program, so you get care built around your needs and surrounded by peers who understand.

We treat depression, anxiety disorders, trauma, PTSD and impulse control disorders. Care starts with a psychiatric evaluation, then your plan can include individual therapy, group therapy, family sessions or medication management. Our therapists use CBT, DBT and EMDR.

If anxiety or depression has led to drinking or drug use, our dual diagnosis treatment brings both tracks together under one plan.

Drug and Alcohol Rehab in Thousand Oaks

Our drug and alcohol rehab treats addiction on an outpatient basis, so you live at home while you attend treatment. Outpatient addiction recovery at Lotus includes individual therapy, group therapy, relapse prevention and case management.

Alcohol Rehab

Our alcohol treatment center offers therapy, relapse prevention and medication-assisted treatment. Vivitrol can reduce alcohol cravings while you attend counseling.

Drug Rehab for Opioids, Stimulants and Other Drugs

We treat opioid addiction, stimulants such as meth or cocaine, cannabis or other drug use. For opioid use disorder, Suboxone or Vivitrol can help control cravings during therapy. Drug testing is part of treatment.

Mental Health and Substance Use Treatment in Thousand Oaks

Lotus Recovery Treatment Center treats mental health disorders and substance use disorders in two separate tracks of care. If you are dealing with both, our dual diagnosis treatment brings your care together under one team.

Our mental health treatment center, alcohol treatment center and drug rehab each run their own groups, so you work alongside people facing similar challenges.

Mental health and substance use disorders often show up together, but not always. Some people struggle mainly with drinking or drug use, while others come to us for depression or anxiety without an addiction. Our outpatient treatment center treats each of these situations.

Your treatment plan focuses first on the condition that affects your daily life the most, then addresses any other concerns as you progress.

I was a client at Lotus Recovery and I can’t recommend this place enough. My time was brief but very impactful. I see recovery in those rooms, people who lift one another up and arnt afraid to be vulnerable with their mistakes to help someone else. My therapy session were very impactful and a lot of covered very quickly because my therapist immediately made me feel safe and heard. 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. I want to shout out a couple of staff members that made everything worth while. Ryan, he was not afraid to bring levity to the group but at the same time speak his peace and call you out when it’s needed. Laura, made me feel seen and heard in a way many haven’t by acknowledging my chronic illnesses and helping me figure out the world around them. Marris with Art, just amazing so good at encouraging peoples creative side and building new hobbies. Chris (both of them) always met me with a smile and it made my day. Darren just really cares about you and there were days I was in his office with an issue and he was just there to listen and try to help in any way he could. This facility truly cares about everyone who walks through there and couldn’t recommend it enough to you or your loved ones
