Leighton Dahl

Leighton is a Registered Provisional Psychologist who provides comprehensive psychological assessments for children, adolescents, and adults. Her work is grounded in evidence-based practice and guided by a thoughtful, strengths-based framework that emphasizes understanding how each individual's brain functions — and how this shapes their behaviour, learning, and emotional well-being.

Her combined expertise in clinical practice and psychological assessment enables comprehensive evaluations spanning cognitive and intellectual functioning, academic achievement, learning differences, executive functioning, and social-emotional development. Through psychoeducational assessment, she helps identify profiles associated with ADHD, anxiety and mood, giftedness, specific learning disorders, and intellectual disabilities. Her tailored, clearly written reports equip individuals and families with the information they need to confidently pursue school planning, accommodations, and applications for government funding, scholarships, and other educational supports.

Leighton's adult assessment practice places strong emphasis on careful differential diagnosis — thoughtfully exploring and distinguishing between possible explanations for a person's symptoms to ensure the most accurate understanding, rather than drawing quick conclusions or applying labels prematurely. She takes a compassionate, trauma-informed approach, examining how cognitive, emotional, developmental, and life experiences collectively influence a person's current functioning.

Her report-writing goes beyond standardized templates, capturing the full complexity of each individual's profile with depth, accuracy, and clarity — translating complex psychological concepts into clear, accessible explanations and practical recommendations. Above all, Leighton's goal is for clients to complete the process feeling understood and validated, with a comprehensive, actionable plan designed to promote measurable progress in the areas where they are currently facing challenges.
