Mark Isajiw

Individuals navigating addiction, trauma, or the slow erosion that burnout brings — as well as couples and families caught in conflict they can’t seem to exit — are the people Mark Isajiw built his practice around. A Registered Social Worker practicing out of Burlington, Ontario, he works with teenagers, adults, men, and women across a range of concerns: alcohol and drug dependency, emotional and psychological abuse, workplace stress, divorce, infidelity, and the long shadows that family-of-origin dynamics cast into adult life.

Mark trained at York University and the University of Toronto, and his clinical toolkit reflects both academic grounding and decades of real-world complexity — including extensive work in rural American communities and twelve years as a clinician with the U.S. Air Force. That breadth taught him to keep each person’s cultural, economic, and social reality at the centre of the work. He draws on CBT, DBT, Mindfulness, Cognitive Processing Therapy, and Solution Focused Brief Therapy, always through a trauma-informed lens. When a couple’s arguments now continue by text long after the room has gone quiet, he brings the same contextual care to understanding what’s actually being said.

Mark describes helping people as a privilege, and that orientation shapes every session. He offers online appointments for those unable to meet in person.
