About Us

Suboxone Clinic

Our mission at Emerald City Treatment Clinic is to provide addiction care and support to men and women who are struggling with opioid dependence.  Our medical model and therapeutic approach exclusively uses medication assisted treatment.  One of the most successful medications for detoxing is buprenorphine/naloxone – a combination of buprenorphine and naloxone, which is well proven to be effective.   We’ll work with you to build a care plan that helps you improve your health and achieve your wellness goals.  We are an outpatient clinic providing addiction treatment in Federal Way, WA and its surrounding areas.  If you’re ready to make the first step and allow us to support you, call our office or schedule a consultation using the online tool.

We believe recovery from addiction is possible.
Let’s stand and fight it together.
