Discover an effective approach to healing and mental health support.

This field is for validation purposes and should be left unchanged.


1 Method has been successfully treating addiction for nearly a decade. Our success is rooted in one simple concept: Individual problems need to be treated in individual ways.

We firmly believe recovery from substance abuse, dual diagnosis, and co-occurring mental illness can be yours – starting today. We also know that getting the right treatment matters. That’s why our philosophy is “Individual problems need to be treated in individual ways.”

What makes a rehab effective is very straightforward: Employing the right care in the right way at the right time. These principles of modality, approach, and timing are integral aspects of our philosophy. 1 Method understands that if any key components are missing from the clinical equation, treatment will stall. We strive to keep your care on track and partner with you to create a strong foundation for your success.

From our effective treatment approach and tranquil, private setting in Southern California to our experienced, compassionate staff and invigorating Health and Fitness Program, we’re confident you can join others whose journey to recovery and healing began with life-changing experiences at 1 Method.

For almost two decades, 1 Method Center has exhibited remarkable leadership and clinical treatment excellence.
