Opioid Epidemic.

November 06, 2017


North Coast Medical Clinic is taking an agressive approach in dealing with and caring for individuals that suffer from an opioid use disorder.  As a suboxone, naltrexone, heroin detox, and vivitrol providor, we pride ourselves in being on the front line of this battle.  This battle can be won!  The combination of education and sometimes medication will contribute to end this epidemic.


We specialize in confidential and personalized treatment. Our program offers convenient outpatient treatment of opiate addiction in an affordable program under the care of a suboxone licensed physician. We can often see patients the same day they make the decision to begin treatment. Our program is designed for motivated, high functioning individuals who have decided to end the cycle of addiction in their life. Our goal is to provide customized individual treatment to help people live a better life in recovery.
