Dr. Tia Ouimet is a licensed psychologist and member of the Ordre des psychologues du Québec (OPQ). She specializes in psychological assessment for children, adolescents, and adults, with particular expertise in Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), learning differences, anxiety, and mood concerns, including assessments in the context of developmental or medical complexity..

​

Her approach is warm and collaborative, with a focus on understanding how the different pieces of a person’s functioning fit together. Rather than looking at test scores in isolation, she considers the whole person: their strengths, the difficulties they are facing, and what may be contributing to them. When a diagnosis is appropriate, it is seen as one part of a broader picture. She takes the time to explain her findings clearly and answer questions, with the aim of making the assessment useful both in understanding what is going on and in knowing what to do next.

​

Dr. Ouimet holds a doctorate in School and Applied Child Psychology from McGill University. Her doctoral research at the Montreal Neurological Institute examined sensory processing and brain development in autistic children and adolescents. Her work has been published in peer-reviewed scientific journals and reflects her longstanding interest in the intersection of brain development and clinical care.

​

Dr. Ouimet brings nearly 15 years of clinical experience across hospital, school, and specialized mental health settings. She completed her clinical training in Child Psychiatry at the Jewish General Hospital and in the Intensive Psychiatric Adolescent Program at the Douglas Mental Health University Institute. She has been part of the Montreal Neuropsychology Center (MNC) since 2017.

​

While assessment is at the heart of her practice, Dr. Ouimet also provides brief therapy and parent consultation, with an emphasis on thoughtful guidance and concrete strategies.
