Thomas Chanzy’s practice covers both litigation (commercial, financial, securities) and white collar crime, at each stage of the proceedings.

Before joining Guillemin Flichy, Thomas worked in the Compliance/Internal Investigations department of a top-ranked US law firm. He has developed a particular expertise in business ethics and compliance (anti-corruption, human rights, exports controls and economic sanctions).
