The organization of this congress is the result of an intense collaboration between the European Society for Trauma and Dissociation (ESTD) and the Association francophone du Trauma et de la Dissociation (AFTD). And as "Unity is strength" is the motto of Belgium, we will meet in Brussels where the event will take place on March 09, 10 and 11, 2023, for a new and bilingual format (English and French).
