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!
