About us

Who we are


We are a group of dedicated and compassionate Masters and Ph.D. level trained clinicians who are registered with the College of Psychologists and Behaviour Analysts of Ontario. We provide psycho-educational assessment, consultation, and psychotherapy services to children and youth. We also have capacity for adult assessment services.

Dr. Mansell’s practice has existed since 2014 in Oxford County, and our clinicians have a strong understanding of local school systems, resources, and community agencies in our region. We use evidence-based practices in our work, and we are committed to our own lifetime learning of ways to best support our clients. You can expect professionalism, empathy, and authenticity in our approach. We will listen to your concerns and come up with a plan together. We strive to form positive relationships with our clients, their caregivers, and others who may be involved with the child or youth.

We see clients for a range of concerns that include: AD/HD, Anxiety, Autism Spectrum Disorder, Behavioural issues, Developmental Disabilities, Giftedness, Learning Disabilities, Social-Emotional Issues and Mood Disorders, Stress and Maladjustment, Trauma, Acquired Brain Injury, Neuropsychological Assessment, and Neurodevelopmental Disorders.
