sleep on the bay dr. dora zalai

DR. Dora Zalai

MD, Ph.D., C. Psych
Practice in Clinical, Health and Rehabilitation Psychology

Dr. Zalai graduated summa cum laude in medicine and she practiced in pediatric neurology. As a physician, she was fascinated by the brain but over time she became even more captivated by the wonders of the human mind. In her interaction with patients, she increasingly realized that our thoughts, feelings, and behavioural habits have a powerful effect on health and happiness but their potential to aid healing is not always appreciated in medicine. This led to her decision to study psychology and earn a doctoral degree in this field. As a psychologist, she practices in the areas of clinical, health and rehabilitation psychology and has unique knowledge in behavioural sleep medicine.

Dr. Zalai feels privileged to work with clients who are on the journey of recovery and self-growth during and after adversities. She works with clients who have sleep problems, fatigue, stress, low mood, depression, anxiety, panic, chronic worry, obsessive thinking, medical or non-medical trauma-related difficulties, post-concussion syndrome, medical illnesses, or chronic pain.
To help clients who have sleep problems, she uses the best available methods to identify what causes the sleep issue and she develops treatment plans that meet the need of individual clients. She offers evidence-based treatments that are short and effective.

Dr. Zalai held positions at the University Health Network, London Health Sciences, St. Michael’s Hospital, St. Joseph’s Health Care (Hamilton) and a number of sleep clinics throughout Ontario. Her research focused on sleep disorders and fatigue in medical conditions, including chronic hepatitis C infection and mild traumatic brain injury. She has educated clinicians and patient groups about the relationship between sleep, fatigue, mental and physical health in Canada, Europe, Asia, Africa and Australia and she developed cognitive behavioural therapy for insomnia treatment programs in the community and hospital settings.
