Facility Highlights

  • Didactic Lectures
  • 12 Step Programs
  • Individualized Treatment Plan


  • Intensive Out Patient (IOP)

    Patients who undergo intensive outpatient treatment continue to live at home and sometimes go to school or work while participating in a highly structured treatment protocol that is focused on ending substance abuse. Programs vary in terms of how much treatment patients receive, how often and for how long. Some facilities design individualized intensive outpatient treatment programs.
  • Medical Detoxification

    Drugs and alcohol have widespread effects throughout your body, including but not limited to the addiction and/or physical/psychological dependence that develops with substance abuse over time. Many organ systems are affected by addiction and will react to withdrawal. The term “medical detoxification” means that there is a trained and licensed medical professional onsite to monitor your vital signs and protect your physical and emotional health as your body goes through withdrawal.

Rehabs 360 Guide


Maryville Addiction Treatment Center (MATC), located in Williamstown, New Jersey, offers medically monitored detox and short-term residential treatment to adults struggling with substance use disorder or dual diagnosis. Founded in 1949, the organization also offers outpatient treatment at their other locations throughout New Jersey. MATC is one of just 17 non-hospital substance abuse treatment facilities in New Jersey to offer medical detox, which make up only 4.6 percent of all treatment facilities in the state.


According to Maryville’s website, the average length of treatment is 20 days, sufficient to begin the recovery process, but with the expectation that clients will continue treatment in an outpatient setting.

The residential program combines evidence-based techniques with 12-step practices and includes individual counseling, group therapy, addiction education, and recreational activities, and well as medication-assisted treatment (MAT) when needed. Specialized services for trauma, grief and loss, veterans, and LBGTQ are also available. In addition, all clients are assigned various housekeeping and maintenance chores to build accountability and enhance their daily living skills.

Outpatient options offered at the facility’s Turnersville and Vineland locations include an intensive outpatient program (IOP) and a standard outpatient program. The IOP offers nine to 15 hours of treatment per week and can include a combination of individual, group, and family therapy. Clients are also expected to attend 12-step meetings. Standard outpatient treatment is much less intensive and consists of one to eight hours of treatment per week, depending upon each client’s need.


Headed by a medical director, the treatment team includes registered nurses, certified social workers, certified alcohol and drug counselors, an admissions coordinator, and other various administrators. The four former clients polled by Rehabs.com to date on MATC's staff qualifications rated them highly.

Staff experience and training: 4.8/5


MTC's residential facility has 76 beds and is set on 40 wooded acres. At the time of this writing, the four alumni surveyed by Rehabs.com about the rehab's facility and activities gave them mediocre to high ratings.

Holistic offerings: 2.8/5
Exercise and leisure activities: 3.5/5
Facility cleanliness and upkeep: 4.5/5


Of the 12 former clients surveyed by Rehabs.com to date, seven gave MTC positive reviews, four gave the facility negative reviews, and one provided the rehab with a mixed review. Clients who were happy with their experience described MTC as an effective and informative program with experienced and caring staff. In a review representative of positive feedback, John called MTC's services "exceptionally good" and added: "The staff is very professional and totally committed to helping you. The food is excellent and abundant and the accommodations are clean and safe."

Unhappy alumni stressed the need for more holistic and extracurricular activities, as well as programming specific to opioid use disorder.

MTC received an average rating of 3.7 out of five stars based on 23 Google reviews. [1] The majority of former clients who left commentary about the facility described it as helpful and effective, including the following anonymous alum who wrote: "The best staff exposure you can ever imagine. These people really know there stuff."

Alumni feedback was less enthusiastic on CiteHealth[2], where three former clients evaluated the facility. One alum noted that while the program gave them "exactly what (they) needed and was looking for," the staff was problematic. The other two reviewers reported negative experiences and complained about a lack of structured treatment and a focus on money.


The majority of loved ones polled by Rehabs.com to date (three out of five) gave MTC negative feedback. Complaints included poor customer service, a lack of communication, and short treatment length. The other two reviewers provided mixed feedback: One loved one noted that while treatment was effective for his wife, he had a difficult time getting in touch with someone to reserve a bed for himself. The other noted that, while the facility was clean and they found it easy to communicate with their family member, treatment was not effective.


According to the facility’s website, fees start at $7,000 for 30 days. MTC also accepts Aetna insurance, and works with other insurance plans on an out-of-network basis.
