David Lussier

My name is David Lussier, and I am a compassionate and dedicated therapist specializing in substance abuse and mental health treatment, with over 27 years of experience. My approach is comprehensive and client-centered, focusing on individuals struggling with addiction, trauma, and mental health challenges such as anxiety, depression, and mood disorders. I am deeply committed to empowering clients to navigate their recovery journeys and achieve fulfilling, healthy lives.

I utilize evidence-based modalities, including Cognitive Behavioral Therapy (CBT), Motivational Interviewing (MI), Trauma-Informed Care, and Dialectical Behavior Therapy (DBT), to address the underlying causes of substance use and mental health concerns. With a strong emphasis on collaboration, I provide a safe, non-judgmental space where clients feel heard, validated, and equipped with the tools needed to thrive. My holistic, person-centered approach tailors treatment to each individual's unique needs, values, and goals.

In addition, I incorporate Strengths-Based, Trauma-Informed, and Collaborative approaches to highlight the inherent strengths and resilience of clients, helping them build upon these attributes to foster lasting change. I recognize the impact of past trauma and ensure the therapeutic process is sensitive to the complex experiences clients may bring into treatment. With expertise in integrated care strategies, I effectively address the interconnected challenges of mental health and substance use.

Treatment is viewed as a partnership, and I work alongside clients to develop coping strategies and recovery goals. My experience spans crisis intervention, relapse prevention, and stressor management in both inpatient and outpatient settings. I also conduct individual, and family therapy to enhance communication and support healthy coping mechanisms.
