A Premiere Short-term Residential Treatment Program in Woodland Hills, California.

OPI's Short-term Residential Program is a personalized, 24/7 transitional living experience for young adults aged 18-28 who are dealing with mental health challenges and seeking to realize their full potential. Our program is located in a peaceful, residential area in Woodland Hills, just outside of Los Angeles, providing a balance between tranquility and access to the city's diverse opportunities.

Our program emphasizes community reintegration and is tailored to meet the unique needs of each resident, providing a safe and structured environment that encourages personal growth and independence. Our comprehensive therapeutic services aim to reduce the need for hospitalization by supporting individuals in their journey towards full community participation.


What makes OPI unique is its combination of strong clinical support alongside community integration. At OPI we treat the whole person, not just the diagnosis.


If you or your loved one is struggling to overcome certain mental challenges and live independently then short-term transitional residential treatment can help. 

OPI STR is a significant first step in you or your loved one’s mental health journey. OPI STR can be an excellent option if you need a higher level of care than traditional outpatient therapy.

I am missing you all greatly, and I mean the entire OPI staff. It was such a great opportunity for me to be able to come to the facility and really learn some great skills that I now put into effect daily without even having to think about it.

It's important to note that while we are not a primary substance use treatment and/or detox program, our transitional residential program is designed to treat multiple conditions and benefit individuals with a variety of disorders.

Addictions Counseling Services

OPI STR’s mental health team understand that many mental disorders/syndromes leave many of our residents open to struggling with addictions. Though we are not a primary substance use disorder/detox facility we understand the importance of treating the whole person, which may include some of our residents who struggle with varying degrees of addiction. Depending on our resident’s needs, our counselors will be able to tailor an appropriate intervention to help provide support.

Pre-Vocational Counseling Services

Part of the mission of OPI STR is to help our resident’s transition back to a more independent living environment with the necessary supports in place to achieve that goal. Our Education and Career Development program provide trainings and skills-based workshops for our residents to address their individual education and career goals.

The Career program supports individualized career exploration using different strategies, which include activities to build career tools and opportunities to discuss ways to engage within the community.

We also support our resident’s educational goals through our Education Program. Our coordinators will assess educational needs so residents can stay on track with schoolwork, and they will be supported in creating an individualized education plan and support the resident in determining next steps in pursuing traditional or non-traditional school.

Meet our team

At OPI, we maintain a high resident-to-staff ratio, ensuring that each resident receives the individualized attention and support they require to achieve their goals. Whether our residents are pursuing academic, vocational, or social aspirations, we are dedicated to helping them build the necessary skills and confidence to succeed.
