GateHouse Treatment 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.

Areas of Specialization

  • 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.

Review by Contributors


Located in Nashua, N.H. GateHouse Treatment offers sober living houses, intensive outpatient programs, and partial hospitalization programs to men who are struggling with addiction. Detox is available at this treatment center.


According to GateHouse Treatment's website, the treatment center offers individualized treatment plans and this New Hampshire facility offers two levels of care. However, treatment starts with an initial assessment. After the assessment, clients begin the detox process.

After detox, individuals start the intensive outpatient treatment program. Clients in this program meet five days a week in phase one, and three days a week in phase two. Programming includes individual and group sessions.

After sessions, residents return to highly structured sober living homes. Residents should be able to apply recovery skills in a real world setting while living at the sober living homes.

Clients can participate in relapse prevention workshops and learn how to cope with the ups and downs of recovery. Residents also participate in various 12-step programs.

The partial hospitalization program is more intense and offers the same level of treatment as an inpatient facility. But, programming is similar to the outpatient programs.


The facility's website notes the treatment team includes therapists, case managers, nurses, and counselors.
