GateHouse Treatment

74 Northeastern Blvd Suite 10, Nashua, New Hampshire, 03060
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.

  • Cognitive Behavioral Therapy
  • Personalized Meals


  • Client & Family Support Groups

    Group therapy is a vital component of addiction recovery treatment, considered as important and effective (sometimes even more so) than individual therapy. Benefits include reducing isolation and loneliness and providing the opportunity to learn from others in recovery. In the addiction setting, group therapy is run by trained professionals who guide participants toward a shared goal of recovery.
  • Family Program

    Research shows that the odds of successful, sustained recovery from addiction are far higher when family members and loved ones are involved in treatment. Drug and alcohol addiction often have genetic roots, whether related to substance abuse, mental illness or both. Family dynamics also play a role and, often, family members are the first to realize a loved one has developed an addiction. Also, it’s important for family members to understand and embrace the lifestyle changes that are required to sustain recovery.
