Alexandre GILLIOEN

Partner & Founder

After having lived  in foreign cities for many years and countries (Brussels, London, Washington, Douala), I decided to create my practice in Lyon because I consider this city as full of opportunities and ideal for a new start. Lyon, a city on a human scale located near Switzerland and Italy, is also a welcoming place for those of us who decide to come and put down roots here. After four years of experience in the field of immigration, I handle on all aspects immigration law.


Senior Associate

After four yours working in Paris as an immigration lawyer, Sarah joined the Defenseur des droits. She worked there to help people who are facing difficulties facing the french administration and on cases where people’s rights were not respected. She then went on to work at the Court d’appel de Grenoble and also for the OFII. Following these experiences Sarah came back to the Bar association and joined our firm as a senior associate with more than ten years experience in the field of immigration law both with the administration and as a lawyer.
