Short cv

Ad Heystek (1956) was born in Rotterdam and grew up in an orthodox Christian (reformed) environment. After attending the pedagogical academy, he studied social pedagogy and developmental psychology at the Nutsacademie in Rotterdam and the Vrije Universiteit in Amsterdam. Furthermore, he specialised as a social worker for adolescents. He has always worked in (professional) education, most of the time in the training of social pedagogical assistance, as a lecturer, supervisor and (student) social worker. In addition, he was and is active in ecclesiastical (management) work. For five years (2004-2009) he worked as a diaconal counsellor in the Christian Reformed churches. Since 1997 he has mainly worked as a lecturer in psychology in higher theological (professional) education. He sees it as his mission to contribute the achievements of the social (psychological) sciences to the forming of professionals for the training and education of the pastor/church worker.
