A meeting of men and women around the same passion, the Mountain.
A common motivation to design, to modernize, to operate.

Mountain development and spatial planning is a story of encounters and human exchanges.
STEM is this desire to share and develop the mountain of tomorrow together.
Our aim is to find conditions of this 4 seasons development for our mountain territories, to pass developed sites on to future generations; job providers respecting natural resources.

STEM’s mission is to perform the management of tourist activities, in France and abroad.
Its internal organization and supporting partners make interventions in all areas possible: all-season leisure, food service, shop management, but also in more specific issues concerning local development and spatial land planning.
