Evergreen Treatment Services

Evergreen Treatment Services (ETS) has been working to transform the lives of individuals and their communities through innovative and effective addiction and social services in Western Washington since 1973. Our interdisciplinary team of professionals includes clinicians with advanced degrees in medicine, psychiatry, nursing, psychology, social work, and counseling.

At our clinics in King, Thurston, and Grays Harbor 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. Street-based outreach services are provided by our REACH Team to vulnerable, chronically homeless adults with addiction in downtown Seattle.
