Our Assessment Team provides psychological and psychoeducational assessment services to young people between the ages of 5 and 19 years and their families. This team also assesses university students who are looking to update older reports.
Elise Ditner has over 20 years of experience providing psychoeducational assessments and support to elementary and secondary students who are experiencing difficulties with issues like ADHD, learning disabilities, anxiety, emotional self-regulation, and difficulties with planning, organization and time management.
Using a combination of assessment and consultative skills, Elise looks beyond the diagnosis to help families and schools really understand an individual’s challenges, and works with them to develop strategies to enhance learning and performance at school and in ‘real life.’
Elise has also worked in a number of hospital and treatment settings, and consulted to a variety of independent schools and public agencies. She provides workshops and presentations for parents, educators and other professional groups on topics such as attachment, motivation, working memory and understanding learning disabilities.
Elise is also a licensed Cogmed coach and has been instrumental in making that program available to individuals and to schools. She is also a member of our Assessment Follow-Up Team.
When not working, Elise enjoys spending time with her family, reading and riding her horse.
