Treatment Center Philosophy

GateHouse Treatment offers highly individualized addiction treatment to men who are experiencing substance abuse issues. A fluid yet essential set of core beliefs animate each and every mode of treatment we deliver. The first is that a profound internal change is necessary for authentic recovery from addiction. The second is that this change must occur in way that’s responsive and respectful to the individual client’s specific needs. Third, we believe that only a holistic approach can affect the necessary change and lead to a fulfilling recovery. Emphasizing responsiveness at all times, our treatment model strives to address the needs of the entire person, not simply those aspects that manifest the symptoms of addiction. Through a combination of traditional and cutting edge methods, GateHouse Treatment helps addicted men build a foundation for a rewarding and long term recovery.
