S. Wayne Duncan, Ph.D.Clinical Psychologist

    Dr. Duncan is a clinical psychologist who works extensively with children and youth who are dealing with attention, working memory, social, mood and anxiety issues.

    He has a broad background in child development and family research and utilizes both individual and family interventions to address areas of concern. His clinical practice includes both diagnostic evaluations and therapy, as well as consulting with parents and schools around the clinical and educational needs of individual students.

    Dr. Duncan utilizes current assessment approaches in cognitive, academic achievement, and social-emotional functioning, as well as current tests for evaluating memory and attention in children and adolescents. His therapy approach utilizes a cognitive-behavioral framework with a strong appreciation of developmental, family, and school factors that can enhance children’s development of skills and coping strategies. Dr. Duncan also regularly participates in school meetings needed for the development of Section 504 plans and Individual Education Programs (IEPs).

    Since fall 2009 Dr. Duncan has offered Cogmed Working Memory Training as part of his practice. Originally developed by Dr. Torkel Klingberg and his team at the Karolinska Institute in Sweden, this evidence-based intervention has proven helpful to many children and youth with working memory difficulties.
