Dr. Jemma Helfman, PsyD., C.Psych. 

Dr. Jemma Helfman has worked with children, adolescents and their families for more than 15 years.  Dr. Helfman believes that early intervention is key to success, whether that be giving children and adolescents specific strategies and skills, skilling up their parents to better help their children through difficult times, or both.  Dr. Helfman takes an individualized approach to interventions, based on her assessment and formulation of why the concerns are presenting.  Dr. Helfman is a thoughtful and empathic practitioner.  When meeting with children individually, she uses games and activities to make the sessions engaging and fun.

Dr. Helfman draws on a wide range of therapeutic approaches to inform her interventions.  These include behavioural theory, cognitive-behavioural therapy (CBT), systemic theories and acceptance and commitment therapy (ACT).  Dr. Helfman is trained in the Incredible Years Parenting Program and in Parent-Child Interaction Therapy (PCIT).  She trained in Selective Mutism with Dr. Aimee Kotrba and has worked as a counsellor at Confident Kids Camp, Michigan for three summers.  Dr. Helfman has specific trainings and experience in selective mutism.  She thoroughly enjoys working with children, adolescents, their families and schools to develop their “brave talking”.

Dr. Helfman completed her doctorate in clinical psychology in London, England and has since worked in the United States and Canada.  She has worked in the National Health Service in England, Community Mental Health in the United States and now works in private practice in Canada.
