Marie- France Renaud, Echomotion Communications founder, first completed her sexology bachelor with a specialization in school and social education. She then pursued her studies and completed a degree in criminology and victimology. Marie-France also studied in communications at the post-graduate level. She followed a psycho-social international and organizational cursus while conducting an ethnographic study on police culture. An important event then changed her life: a child with selective mutism in her close circle. Realizing that this condition was unknown by paediatricians, neuropsychologists and language therapists, Marie-France perfected her knowledge for many years. She opened a clinic in Vaudreuil (Québec, Canada) and founded the Selective Mutism Canadian Society.
