Elsa Costa

I am an internationally certified mediator, dedicated to helping businesses, public institutions, and teams find constructive, lasting solutions, and open new perspectives through listening and dialogue.

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 an independent mediator with public institutions, businesses, and teams experiencing situations of tension or conflict. Since 2024, I am one of two mediators of the mediation service at the OECD in Paris dealing with workplace conflict prevention and resolution in a multicultural environment and providing conflict 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.
