An evidence-based program combining knowledge, structure, and support.


Improving the lives of individuals and families affected by alcohol and substance misuse by establishing the goal of long-term recovery.

Remnant House utilizes the Matrix Model Intensive Outpatient Programs (IOP). With more than thirty years of research and development, this 12-week evidenced based program offers a comprehensive, individualized approach to recovery.

Our program addresses five core clinical areas within five components: Individual and Conjoint Sessions, Early Recovery Skills Group, Relapse Prevention Group, Family Education Group, and Social Support Group. There is also an educational component available for patients using Medication-Assisted Treatment (MAT).

It is not necessary for every individual experiencing alcohol and substance misuse to attend an inpatient facility. An Intensive Outpatient Program, such as what we offer at Remnant House, allows patients to conveniently continue with their daily responsibilities while beginning their journey of recovery

Upon completion of the program, patients are given the opportunity to join a fellowship that assists and supports their aftercare journey.

Individual & Conjoint Sessions

Offered throughout the program are one-hour weekly sessions with a counsellor. Patients may invite significant others or support persons to attend these sessions.

Early Recovery Skills Group

This group meets twice weekly during the first four weeks of treatment. Meetings are approximately 90-minutes in length and teach patients the basic skills they need to achieve initial sobriety. Patients are introduced to cognitive behavioral interventions, as well as learn about 12-step support and other spiritual or self-help involvement.

Should patients become unstable during treatment or experience a lapse, they are encouraged to return to the Early Recovery Group anytime during the 12-week program.

Relapse Prevention

This group meets twice weekly after Early Recovery Skills Group. These 24 meetings are approximately 90-minutes in length and continue for the duration of the 12-weeks of treatment. The sessions are designed to assist patients in maintaining abstinence by providing information, support, and guidance as they proceed through recovery.

Social Support Group

This group is ongoing and meets weekly. Various topics are discussed relating to family and addictions. Patients may continue with this group after completion of the program as they become part of the Remnant House fellowship.

Site-Specific Group

This is an open group that covers a diverse range of topics including: mindfulness, 12-Step Recovery, co-occurring disorders, anger management, life skills, relationships, PTSD, trauma, grief, anxiety, and depression.

Family Education Group

This group meets once a week, Wednesday. Patients and family members come together in sessions designed to be interactive. Three videos are included which are used for topic discussions.
