I graduated from the clinical psychology program at the University of Waterloo in 1996. Practicing in the community as a registered psychologist for over 20 years, I have gained invaluable knowledge and clinical expertise. My workplaces have included hospitals, community mental health centres, a school board and private practice. My approach to treatment focuses on using empirically supported treatments such as Cognitive Behaviour Therapy (CBT), Acceptance and Commitment Therapy (ACT), and mindfulness.

In addition to the clinical  work I have had lifelong involvement in athletics as a participant and as a coach of youth teams.
