Applauded by the international press as being one of the best negotiators in the world, Marwan Mery works with businesses, government organisations and NGOs, of any size, to resolve complex situations that include critical cases (kidnapping and ransom, extortion, suicidal persons, collective internment) as well as social conflict, commercial negotiation, diplomatic relations or patient-physician relations (where, for example, a patient refuses to comply with their treatment).

In 2013, he founded ADN Group with his associate, Laurent Combalbert. Shortly after this became the first worldwide network of professional negotiators. In 2016, their life experience inspired the Franco-American television series Ransom –produced by Frank Spotnitz (X-Files). The series recounts the life and work of a crisis negotiator. Both of the French negotiators act as technical advisers for the production.

Marwan Mery is the author of several successful publications and a lecturer at HEC, Paris. He is also the chairman and chief-instructor of HCNIA, Hostage and Crisis Negotiation International Academy, an academy that trains and raises awareness in elite units around the world for a peaceful solution, to critical situation, through negotiation.
