About Mark

I hold a Master's in Clinical Psychology and Honours Bachelor of Science in Psychology from York University, where I trained in psychotherapy and researched human wellbeing at one of Canada's largest positive psychology research labs.

I currently practice at The Clinic on Dupont and Turning Point Psychology, providing evidence-based psychotherapy with a strong emphasis on measurable outcomes. I use a Feedback-Informed Treatment approach with Deliberate Practice to track how clients are doing and quickly adapt to their needs.

Before entering private practice, I spent years in hospital and research settings — as a research associate at Sunnybrook Health Sciences Centre and Baycrest Health Sciences, where I led multi-site research studies and published in world-leading journals. I trained at the York University Psychology Clinic and provided crisis intervention through Toronto's Distress Centre.
