Marcel den Boer

Marcel has many years of experience working for the Ministry of Defence and the Ministry of Justice and Security, both on a national and international level.



His knowledge and skills in the fields of aviation security, behavioral recognition, and defensibility resulted in the establishment of his own training agency Training of Mars, which has clients in aviation, health care, and training companies. His approach is mainly aimed at the prevention of escalations: therefore, recognizing deviant behavior and situations is an integral part of the training.



As an aviation security trainer and aggression training, Marcel is in possession of a teaching qualification.
