Dayna Lee-Baggley, PhD, exercises regularly and rarely enjoys it. She is a regular runner who competes in 10K races and never gets a runner's high. She drinks green smoothies and hates vegetables. Every time her kid asks her to go do some physical activity (biking, swimming, etc.) she thinks 'crap, I don't want to do that,' and she does it anyway.

Dayna is also a registered clinical psychologist, who specializes in health. She holds an assistant professor appointment in the department of family medicine, and cross appointments in the departments of surgery, and psychology and neuroscience at Dalhousie University; and an adjunct professor appointment in the department of industrial and organizational psychology at Saint Mary's University. She works as a clinical health psychologist at the Nova Scotia Health Authority for the multi-organ transplant program. She is director of the Centre for Behaviour Change, which conducts research and training in chronic disease management. She is an internationally recognized trainer in acceptance and commitment therapy (ACT). She is president of the Atlantic chapter of the Association for Contextual Behavioral Science (ACBS), and vice chair of the Halifax Chapter of the Canadian Obesity Network. She was the recipient of the 2017 Women of Excellence Award for her contributions to health,sport, and wellness (Canadian Progress Club Halifax Cornwallis). Her areas of expertise include facilitating health behavior change, managing and treating obesity, adapting to chronic health conditions, professional resiliency/burnout prevention in health care providers, and healthy workplaces.
