Green and Purple Abstract



Dr. Keating

Dr. Trista Keating is a specialist in the assessment of toddler, child, and youth Autism Spectrum Disorder (including its different presentation in girls), learning disorders, ADHD, anxiety/depression, and a wide variety of other conditions.

Dr. Trista received her undergraduate degree in psychology from McGill University and completed her Ph.D. in School Psychology at the University of Alberta.


Following her education, Dr. Trista held several roles in school psychology before returning to a university setting. In her position at the University of Calgary, she taught courses on topics including behavioural supports, educational psychology, the educational assessment of exceptional children, and evidence-based interventions for child/youth social-emotional disorders. She also was chosen to supervise the graduate students and operations of the university clinic.

For more than a decade, Dr. Trista has worked in private practice by drawing on this academic and hands-on experience to create positive outcomes for her clients.


As a mother, daughter and friend to many children, adults and families with learning, emotional and behavioural challenges, she has come to understand the difficulties families encounter more intimately. This experience continues to inform her client interactions as she more fully appreciates many sides of the process.

At Acorn Psychology, Dr. Trista Keating handpicks exceptional student psychologists based on their education, work experience and client interactions. This thorough process has resulted in the creation of a team that provide the highest quality of care through their expertise, professionalism and empathy. Dr. Keating is devoted to being in the office daily, offering hands-on supervision, consultation, and review for her team. Though Dr. Keating may not perform every stage of the process, she is heavily involved in the work performed by the psychologists and discusses each client in detail them. At Acorn Psychology, your child’s well-being and success are our top priorities and Dr. Keating has complete confidence in every member of her team.
