Guy Tempereau est le Président Directeur Général du Groupe SERIS

Chairman of SERIS

Created in 1958, the company, having fallen into great difficulties, was taken over by Guy Tempereau in 1976. Thus at the age of 23, an accountant by profession with 6 years of experience, Guy wagered on the future. The development of the company would be rapid, because he knew that success lay in the diversification of activities and in geographic expansion.

In 30 years, Guy has thus taken hold of a small local company of thirty employees, driven it to the very top of its profession and given it a European dimension, not only by the successive acquisitions of numerous companies, in France, Belgium and The Netherlands, but also thanks to a constant organic growth.

Since its partnership with the group Amarante in October 2015, Guy TEMPEREAU increases the international  development of the group  and follows his original goal to propose to his clients all form of security.

Guy TEMPEREAU decided simultanously to name by its side his two daughters, Celine TEMPEREAU-SAUVAGE and Audrey PROU as Deputy Chief Executive officers, carrying,  therefore, a vision of the future and a long term policy as long term projects  in accordance to the family willingness.
