Hi, I'm Mark!

I am a Registered Social Worker and Psychotherapist. I hold a Bachelors Degree in Social Work from York University and a Master’s Degree in Social Work from the University of Toronto. I am also a member of the Ontario College of Social Workers and Social Service Workers, as well as the Ontario Association of Social Workers.

I take a very client-centred approach to providing therapy services and am well-versed in utilizing principles of Cognitive Behavioural Therapy (CBT), Mindfulness, Cognitive Processing Therapy (CPT), Solution Focused Brief Therapy, and Dialectical Behaviour Therapy (DBT) in a trauma-informed manner. 

I also have a wealth of experience ranging from brief, Employee Assistance Program (EAP) work to longer term, trauma-focused counselling with individuals, couples and families. I have spent a significant amount of time in the United States working in rural community settings as well as 12 years as a clinician and officer in the U.S. Air Force. This experience has taught me the critical importance of taking clients’ social, economic, and cultural contexts into account when collaborating with them in finding pertinent solutions.

I strongly believe that providing assistance to people is a privilege and an honour and I bring this mindset to every session.
