Dr. Terri Barriault, Ph.D., C. Psych.

I am a Clinical & School Psychologist with over 30 years of experience helping children, youth and their families. Currently a partner at Roots and Wings Psychology, I was formerly the Clinical Director at Child & Community Resources. I’m passionate about capacity building in the North; teaching, training and supervising professionals in psychology and behaviour analysis, in order to help meet the tremendous needs of our young people. I’m a strong community collaborator, especially if it means bridging gaps in service to meet client’s needs. People tell me I am calm, compassionate, and I’m confident that I make evidence-informed judgments in the best interest of my clients. I’m a true Northerner as I love the outdoors, pets and wildlife, and travel with my husband and two daughters.
