Elsa Costa

I am a nationally accredited Mediator – French Administrative Courts and Paris Judicial Court of Appeal - and International Mediation Institute certified, practicing in France and internationally.

Before becoming a mediator, I served as a judge for 15 years in Administrative Courts where I had the opportunity to observe firsthand the complexity and the destructive dynamic of conflict.

For several years now, I’ve been working as a freelance mediator with public services and businesses experiencing situations of tension or conflict. My goal is to help them to open new perspectives through listening and dialogue.

Since 2024, I am one of two mediators of the mediation service at the OECD in Paris dealing with workplace conflict resolution in a multicultural environment and providing conflict training and coaching with staff and managers.

I also work as a lecturer at universities and as an ADR trainer for educational institutes.

I offer mediations in French, English, Spanish and Catalan.
