Treatment Approach

Our highly-skilled clinicians and support staff provide exceptional care for individuals addicted to drugs and/or alcohol, with or without other coexisting mental health conditions.

Care at Naukeag focuses on group and individual therapy, as well as medication consultations as may be appropriate. We utilize behavioral therapies such as cognitive behavior therapy and integrated group therapy.

We work with patients to develop tailored treatment plans that put individuals on the path to recovery by offering support as they reclaim their independence from addictive substances, learn to manage the stress of an active life without returning to drug and alcohol dependence, and attain personal, career, and recovery goals.

Tobacco use is addressed as a substance use disorder and patients are encouraged to quit as part of recovery. Nicotine cessation treatment, including medications and behavioral interventions, is available. Tobacco products are not allowed inside the buildings, though there is one designated smoking area outside. Cigars, chewing tobacco, and e-cigarettes are not allowed on the premises.
