Dr. Mark Petter
I am a clinical psychologist registered with the College of Psychologist of Ontario. I received my Ph.D. in clinical Psychology from Dalhousie University in 2014. Since graduating I had been employed at Victoria Hospital with the Traumatic Workplace Program until entering private practice.
My practice focuses on providing assessment and treatment to adults with a variety of physical and psychological difficulties. I work from a cognitive-behavioural perspective and I have also received training in mindfulness-based treatments, including completing professional training with Dr. Jon Kabat-Zinn. I am particularly interested in helping individual's cope with stress, injury, illness, and pain. A goal of my practice is to provide my clients with the most scientifically supported treatments available.

Heather Hargraves has her M.A. in counselling Psychology from Western University and is registered with the College of Psychologists of Ontario as M.A., C.Psych.. Her Master 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 Ontario.

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.
Dr. Nancy Davis
I am a clinical psychologist registered with the College of Psychologists of Ontario. I received my Ph.D. in clinical psychology from the University of Wisconsin-Madison in 2002 and completed my post-doctoral training at the University of Michigan in 2004. I moved to London in 2009 and I'm excited to be a part of Dr. Biederman's practice and to serve the mental health needs of the London Community.
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. I often work with people with chronic pain, sleep difficulties, and exposure to trauma. I have a particular interest in working with people who have or have had cancer, and their caregivers.
Dyana Castillo, BSc, PhD candidate(Supervised Practice)
Dyana Castillo is working under Dr. Tamara Biederman's supervision at our practice.
I am very interested and motivated in helping people lead the lives they are interested in. I am curious about everything that goes into making individuals who they are, and I use this curiosity to better understand the people with whom I work. My practice focuses on providing evidence-based assessment and intervention for adults. My clinical interventions are heavily influenced by psychodynamic and emotion-focused therapies because issues of emotion regulation and expression are highly common in mental health conditions, and they often develop earlier on in life. Ultimately, I let individuals’ needs guide the nature of the treatment, as well as the pace of our work together. Where relevant, I also incorporate my knowledge of social systems in society (e.g., family) and culture to better understand individuals with whom I work. I am grateful to be let into an individual’s world so that we can find a way to work towards a healthier quality of life.
