Our experience. Maryville was the first nonprofit addiction agency to open in the state of New Jersey and is recognized as a leader in the treatment of substance use and co-occurring mental health disorders. For over 70 years, our holistic, evidence-based treatment approaches have helped bring hope, health and healing to those suffering from opioid, alcohol and other addictive substances.
We are licensed by the state of New Jersey, accredited by the Commission on Accreditation of Rehabilitation Facilities (CARF), and a member of the National Association of Addiction Treatment Providers. Our treatment programs make sustainable recovery possible through individualized treatment plans and ongoing support services. Maryville staff devote themselves each day to helping people with substance use and co-occurring mental health disorders reclaim their lives and maintain long-term recovery.
Our team. Our treatment teams bring specialized expertise and a shared commitment to utilizing evidence-based practices for long-term recovery. Due to our staff’s education, experience, compassion and commitment, individuals who have been served by Maryville consistently document high satisfaction levels with our programs and services.
Our accessibility. Our outpatient programs in Turnersville and Vineland are accessible by public transportation as well as through telehealth. Our inpatient programs, located in Williamstown and Pemberton, are able to coordinate transportation when necessary.
Our mission. Everything we do is driven by our mission to provide comprehensive, high-quality drug and alcohol addiction treatment and co-occurring mental health services. Maryville is a private, non-profit organization governed by a volunteer Board of Directors. As a non-profit service provider, our first priority is always our clients’ well-being, not financial gain.
Founded in Williamstown, New Jersey in 1949 by Father A. Bennett Conway to help alcoholic men become sober, Maryville Addiction Treatment Center has evolved over the years to offer a full continuum of care to adults and their families. Today, the 80-bed Williamstown Campus houses medically monitored withdrawal management and short-term residential treatment for men and women. In 1979, Maryville opened its first outpatient office, now operating in Turnersville, followed by the Vineland office in 1998. Also in 2018, Maryville assumed operation of Burlington County’s 54-bed residential addiction treatment facility for men, now known as Post House at Maryville, which offers withdrawal management, short-term, and long-term treatment. Throughout its treatment continuum, Maryville provides co-occurring treatment for individuals with co-occurring mental health disorders, via licensed counselors and Advanced Practice Nurses (APNs). Maryville also offers Medication Assisted Treatment via APNs and physicians.
Maryville served as Gloucester County’s designated Intoxicated Driver Resource Center provider for thirty years. We are the addiction services provider for the Burlington County HOPE One mobile unit, partnering with the Sheriff’s Office, Health Department, and Department of Human Services to bring education, screening, peer support, naloxone, and direct treatment access to the community. Last year, with funding from Camden County, Maryville developed partnerships with two Camden City homeless shelters, basing a Certified Peer Recovery Specialist onsite once a week to conduct assessments and recovery support services. This creates easier and swifter access to the treatment many shelter clients need but often won’t access on their own. Maryville hopes to expand this to other counties and shelters in the future.
Governed by a volunteer Board of Trustees, the organization employs over 160 individuals and holds more than 30 contracts with 14 entities including The New Jersey Division of Mental Health and Addiction Services, Federal Probation, Intensive Supervised Probation (ISP), Veteran Administration, Medicaid/DXC, and the Counties of Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, Mercer, Ocean and Salem.
