Trained at the Ecole Spéciale des Travaux Publics (B2003), then graduated from the Ecole Spéciale d'Architecture (2018), Damien began by creating his own graphic design and perspective company for architecture.

He joined the Patriarche agency in 2004, and became managing director in 2006. As a developer and driven by the desire to adapt the practice of architecture, he broadened the agency's skills, created various subsidiaries, and invested in various development sectors (real estate, communication, digital, etc.) that were instrumental in the emergence of an "augmented architecture".

Today, as President, Damien is responsible for the strategic management of the group while continuing to manage specific projects. He is a member of the weekly design board.
