Welcome to Evergreen Treatment Services (ETS)

We have been working to transform the lives of individuals and their communities through innovative and effective addiction and social services in Western Washington since 1973.

At our clinics in King and Thurston counties, ETS offers medication-assisted treatment for adults with opioid use disorders. We provide methadone and buprenorphine-based medications with supportive wraparound services including medical monitoring, counseling, and drug screens.

We also support the REACH team which provides street-based, case management, and outreach services to adults living outside in the greater Seattle area.
