Dialectical Behavioural Therapy is an evidence-based treatment developed by Dr. Marsha Linehan for Borderline Personality Disorder (BPD) as well as other diagnoses and symptoms such as anxiety, mood disorders, substance use, eating disorders, suicidal thoughts, self-harm, trauma, etc. Participating in a comprehensive DBT program is shown to have a positive impact on the above mentioned and other common difficulties. It is critical to be sure that your DBT therapist is truly qualified to practice DBT.
When DBT is not done as designed, the results may be inadequate and cause the person to lose hope in treatment. Therefore, getting the best outcomes possible from DBT requires a comprehensively trained DBT therapist who provides treatment that adheres to the DBT model. We are the only centre in Montreal to offer comprehensive DBT therapy. We are also the only centre in Quebec with a DBT Linehan Board of Certification™ Certified Program and Clinicians.

DBT-C is a specialized adaptation of Dialectical Behaviour Therapy designed to support the emotional and developmental needs of children. This evidence-informed approach focuses on helping children build effective coping skills to manage intense emotions, while also guiding parents in supporting their child’s progress. Though relatively new, DBT-C has shown promising results in improving emotional regulation and strengthening family relationships—empowering children to thrive at home, in school, and with friends.
DBT-C is an adaptation of DBT designed for children aged 6–12 who struggle with intense emotions, impulsivity, and behavioural outbursts. It teaches children effective coping strategies and equips parents with tools to support their child’s emotional growth at home.

Build a life worth living, without PTSD.

Comprehensive DBT is not suitable for all individuals with eating disorders, nor are all eating disorder clients appropriate for DBT. However, DBT may be a strong option when standard, evidence-based treatments have been ineffective, when there are co-occurring mental health conditions, or when difficulties with emotion regulation are a core part of the disorder.
We offer DBT-informed treatment for a range of eating-related concerns, including:
Treatment Goals May Include:

Radically Open Dialectical Behavior Therapy (RO DBT) is an innovative, transdiagnostic treatment developed by Dr. Thomas Lynch. It is specifically designed for individuals struggling with disorders characterized by excessive self-control—also known as overcontrol (OC). These include conditions such as anorexia nervosa, chronic depression, and obsessive-compulsive disorder (OCD), which are often difficult to treat using traditional approaches. RO DBT combines individual therapy sessions with skills training classes and focuses on five key features of overcontrol:
This evidence-based approach helps clients increase openness, flexibility, and genuine social connection—core components of emotional well-being.
In Radically Open Dialectical Behavior Therapy (RO DBT), psychological health is viewed as a balance of three interrelated traits:
At the heart of RO DBT is the concept of Radical Openness—a central philosophy and teachable skill. Radical Openness is both a mindset and a behavior: it involves actively seeking out what we don’t know about ourselves in order to grow, adapt, and connect with others. Practicing Radical Openness fosters humility, enhances learning, and strengthens relationships by modeling a genuine willingness to be influenced by others and by the world around us.
RO DBT includes both weekly group sessions and individual therapy, led by clinicians trained in this evidence-based approach:
Our 10-week parent group is designed for caregivers of teens or young adults who struggle with emotional dysregulation, including those who engage in risky behaviors, self-harm, or experience suicidal thoughts.
This group provides education on Borderline Personality Disorder (BPD) and related conditions, introduces the principles of Dialectical Behavior Therapy (DBT), and offers practical strategies for supporting your child with compassion and confidence.
