Altergis tells us Gérard Leseur left the Veolia group in 2000 to found what was to become Altergis, in the Bouches du Rhône. This was a reasoned decision conceived after a sudden insight he had when he was a teenager. The group working in the energy and fluids field (except for nuclear) is developing continuously, well beyond the regional sphere. A genuine success story that makes people want to become entrepreneurs!
