Registered Provisional Psychologist

Leighton Dahl

Leighton Dahl is a Calgary psychologist who provides comprehensive psychological assessments for adults seeking diagnostic clarity — including ADHD, executive functioning, and diagnostic clarification for a range of mental health concerns.

Leighton brings a warm, steady, and collaborative presence to the assessment process. She understands that pursuing an assessment can feel vulnerable, so she creates a space where clients feel understood rather than evaluated, and where the goal is genuine insight into how their mind works.

Her assessment work centers on adults seeking clarity around attention, executive functioning, mood, and anxiety. Whether clients are looking for personal understanding, confirmation of a longstanding suspicion, or documentation to support workplace or academic accommodations, Leighton tailors each evaluation to their specific questions and goals.

Each assessment draws on clinical interviews, standardized measures, behavioural observations, and relevant background information to build a holistic understanding of the individual. Clients leave with a clear feedback session, practical recommendations, and a written report designed to support informed next steps.
