Dr. Jennifer Hunter, Ph.D., C. Psych. (Supervised Practice). Hello, and welcome. I look forward to learning about the challenges you’re facing, your life journey, and your gifts and hopes for the future. In my experience, people who are considering assessment or therapy have something ‘right’ with them rather than something ‘wrong’ with them.

I work with adults and couples, and I provide psychological assessment and psychotherapy. I start by developing a warm, appreciative relationship, and then I tailor our work together based on your needs and preferences (this is often referred to as integrative psychotherapy). I have been trained in multiple therapeutic modalities including Emotion-Focused Therapy, Narrative Therapy, and Motivational Interviewing. I have had the honour of working with a broad range of adults pondering a variety of existential struggles, and have worked most often with individuals who are questioning in the areas of trauma, disordered eating, life transitions, and intimate relationships. I am presently working as a Psychologist under Supervised Practice – this is a mandatory year of supervised clinical work all Psychologists undertake after completing their Ph.D. I also teach graduate Master of Social Work classes at the University of Toronto on Narrative Therapy and Emotion-Focused Therapy. I completed my MA and Ph.D. in Clinical Psychology at York University. During my studies, my SSHRC-funded research investigated what helps us be creative, and how to prevent boredom in the post-secondary classroom. Prior to my MA and Ph.D. in Clinical Psychology, I completed a Master of Social Work and an undergraduate degree in English literature at the University of Toronto. I love nature and include my adored dogs in my network of cherished human beings. I look forward to the privilege of meeting with you.
