Addiction Resource Score
Scoring is assigned by a proprietary system which helps surface key metrics that determine quality. The 10-point scale factors in categories such as operations, customer satisfaction, and trust metrics.
We understand that choosing an addiction treatment center can be overwhelming, especially with so many options, promises, and marketing messages. That's why we've developed a clear, standardized rating system designed to cut through the noise and highlight what truly matters: safety, quality of care, and transparency. Our goal is to give individuals and families the information they need to make confident, informed decisions during a critical time.
In this guide, we explain exactly how we rate treatment centers—from accreditation and staff credentials to therapy options, facility environment, and family involvement. You'll see how we assign scores, award badges, and update listings to ensure accuracy and fairness. Most importantly, our system focuses on elevating centers that prioritize ethical, evidence-based care, not just those with the best marketing. This way, you can trust that the ratings you see reflect meaningful standards that help you find the right fit for lasting recovery.

MedMark Treatment Centers – Fairfield is a private clinic that specializes in treating opioid use disorder (OUD) with accessible and adaptable outpatient therapy. It is situated in Fairfield, California, next to Alan Witt Park. MedMark provides tailored therapy that meets clients where they are in their recovery path, catering to the particular requirements of each adult seeking recovery. Given that each addiction situation is unique, MedMark is dedicated to providing focused, tailored treatment that assists clients along their journey.
One of MedMark’s main offerings is its outpatient treatment programs, which let patients get therapy on a regular basis while still living at home. For individuals with less severe symptoms, this method is often suggested since it allows them to continue with their everyday obligations while participating in planned rehabilitation activities. A crucial element of MedMark’s strategy is the integration of family, group, and individual therapy. In addition to offering clients the chance to support one another in a peer environment, these sessions educate participants on the nature of addiction and provide coping mechanisms and relapse prevention tactics. Family therapy places a special emphasis on giving family members the skills and information they need to help their loved ones become well.
Additionally, MedMark promotes the use of Medication-Assisted Treatment (MAT), which combines thorough counseling services with FDA-approved drugs like buprenorphine and methadone. MAT helps clients focus more intently on their recovery journey by reducing cravings and withdrawal symptoms. This comprehensive approach addresses the psychological and physical elements of addiction in order to encourage long-term health and recovery.
Numerous insurance policies are accepted by MedMark Treatment Centers, including state Medicaid, Medicare, and VA coverage. In order to guarantee the greatest assistance possible, prospective clients are advised to confirm their coverage details prior to beginning treatment, given the variety of both in-network and out-of-network advantages.
Since 2006, MedMark, now a division of BayMark Health Services, has expanded from three programs in Northern California to more than 50 sites nationwide. In spite of this growth, MedMark is unwavering in its dedication to providing compassionate care and working to improve the lives of patients, families, and communities. In addition to medication assistance therapy (MAT), MedMark’s opioid treatment programs include drug abuse counseling and other supportive services that help people in recovery feel hopeful and lead better lives. The facility is renowned for providing patients from all backgrounds with the respect and care they need in a secure, judgment-free atmosphere.
