Dr. Kortstee is licensed with the College of Psychologists of Ontario. She received her first training in clinical psychology and clinical neuropsychology at the University of Tilburg in The Netherlands. Subsequently, she earned her Ph.D. in Clinical Psychology (Neuropsychology Track) in 1998 at the University of Windsor in Ontario. She has worked in a number of medical and mental health settings in The Netherlands, United States, and Canada.

In her work, Dr. Kortstee uses her knowledge of brain development and brain functioning to help children, youth and their parents understand why they are experiencing difficulties. Neuropsychological assessments help to understand a child’s learning, social functioning, and emotional and behavioural regulation from the perspective of brain development and functioning.

A neuropsychological assessment includes all components of a psychoeducational assessment, but it also looks a bit deeper into areas of functioning that may underlie the difficulties a child or adolescent may be experiencing. A neuropsychological assessment typically includes assessment of the following domains:

  • Fine motor functioning
  • Visual, auditory, sensory perception
  • Visual and auditory attention
  • Language and visual processing
  • Visual-motor integration
  • Memory
  • Executive functioning (e.g., problem solving, planning and organization, mental flexibility)
  • Intellectual functioning
  • Academic achievement
  • Social, emotional, and behavioural functioning.

The results of a neuropsychological assessment not only provide good insight into a child’s profile of strengths and weaknesses but also help to understand why a child is experiencing difficulties. This leads to effective recommendations for school programming and treatment planning, which often carries over to everyday life. Throughout the years, Dr. Kortstee has had extensive experience liaising and collaborating with schools in order to best implement the recommendations that stem from an assessment within the school environment.

Dr. Kortstee uses a warm and collaborative approach in working with children, adolescents and their families. She enjoys helping young people in finding their strengths and developing strategies to overcome their challenges. She is creative and always seeks to use the latest evidence-based practices in her work with them.

Other professional interests include the provision of clinical teaching and consultation, professional outreach to the primary care community, as well as the clinical training and supervision of psychology students and residents.
