I am a clinical psychologist registered with the College of Psychologists and Behaviour Analysts 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 individuals cope with stress, injury, illness, and pain. A goal of my practice is to provide my clients with the most scientifically supported treatments available.

Dr. Nancy Davis

I am a clinical psychologist registered with the College of Psychologists and Behaviour Analysts 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.
