Dr Linda Nicholson is a clinical psychologist based in Canberra, Australia, with over 20 years of clinical experience and more than 15 years as a supervisor, trainer, and clinical educator. Formerly the Psychology Clinic Manager at the Australian National University, where she trained clinical psychologists, Linda now provides supervision, consultation, and training to psychologists both across Australia and internationally.

Linda’s work is deeply grounded in acceptance and commitment therapy (ACT) and integrates behavioural, cognitive, and compassion-focused approaches.
