​​​​​​​​​​​Heather Hargraves graduated with her MA in Counselling Psychology from Western University, in London, Ontario, Canada. Her Masters thesis investigated how neurofeedback can help those struggling with various forms of trauma. Heather also holds a BAH in Philosophy from the University of Windsor. Between her degrees Heather worked as a yoga instructor,  and meditation teacher. Heather's strength lies in her understanding of the neurological basis of various mental health disorders and her ability to explain and educate how various forms of therapy, including mindfulness therapies, can be used to address specific needs. Heather is particularly interested in how neurofeedback and heart rate variability therapy can help a client move through various issues that have proven to be slow to respond to traditional talk therapies alone. Heather will be working under the clinical supervision of Dr. Tamara Biederman.

I am a clinical psychologist registered with the  College of Psychologists of Ontario. I am licensed to provide psychological services in the areas of Clinical Psychology, Counselling Psychology, and Rehabilitation Psychology.

​My work with patients is grounded in the feminist principles of collaboration and respect for the individuals' own authority regarding their experience. My work includes acknowledging the interaction between the individual and the systems that the person is a part of, such as family, culture, and work environment, and how that interaction contributes to the person's lived experience. I value focusing on my patients' strengths and capacity for resilience, even though much of the work may involve engaging with areas of distress including depression, anxiety, and grief.
