Dillon is a registered member of the College of Psychologists of Ontario certified to work as a clinical psychologist with children, adolescents, and families. For over a decade, Dillon has provided assessment and therapy services to young people of all ages who struggle with anxiety, depression, behavioural difficulties, ADHD related challenges, learning difficulties, school refusal, and other common challenges. He is also versed in providing trauma-informed services to children and families who have experienced traumatic events. Depending on the nature of presenting concern, Dillon may work with children and parents together, children alone (most common with older adolescents), parents alone, or entire families. In other words, he provides a variety of services including individual therapy for children (with parental involvement), parenting support, and family therapy. Dillon primarily relies on cognitive behavior therapy when working with children. However, he also provides conjoint (dyadic) therapy with parents and children, including those under 6 years of age. For families who are experiencing relationship difficulties, he primarily utilizes both structural and emotion-focused family therapy.
