Jean-Marie Mettraux - Partner


Originally from the French part of Switzerland, I have been based in Zurich since 2006. After my master’s degree I started working for the Claims Resolution Tribunal of the Holocaust Victim Assets Litigation against Swiss Banks and other Swiss Entities. After this process was over and the assets redistributed, I started working for an international law boutique in Zurich specializing in cross-border tax service as a member of the US team that focuses on individuals and trusts with US tax problems. After a few years I was promoted to Director of a new US tax accounting firm I helped found. I managed the firm from the beginning with the partners and within 1.5 years developed it into a successful US tax firm before deciding to create my own company using my US and international compliance and tax knowledge.
