Marc Berthier, Elise Berthier, Pierre Garner, Frederic Lintz & Anne Klepper are called it Studio because they are no hierarchy between them. This delicate balance depends upon a tension, a behavior that carries its own limits. Studio also implies that they work on the projects all together and that they all participate to the initial creation. The first stage of presentation is fed by their five personalities, their five approaches. Nevertheless, regarding the basis, the core of the project, everybody’s approval is always required.
