FRÉDÉRIC TISSERAND Deputy General Manager – Chief Operating Officer

Passionate about aviation having graduated from business school, Frédéric founded his own company in the aviation defence sector in 1989. After twenty years of activity and specialisation in the field of French military aircraft support, he was faced with the logical choice of joining forces with Sofema to participate in the creation of what has become the French leader in 1st generation overhauled-equipment and spare parts supply. As Deputy General Manager of Sofema, Frédéric brings his expertise to bear on successive successful realisations that confirm Sofema’s position in the marketplace.



After graduating from the Ecole Spéciale Militaire de Saint-Cyr, the French military academy in 2008, Christian Kamara began his career as an officer in specialised units where he acquired a solid international experience, mainly in Africa and in the Middle East.
After ten years in operations, and searching for new challenges, he joined Sofema in 2016 as Sales and Business Development Manager, with the aim of opening up new markets and contributing to the growth of the company in the terrestrial and aeronautical fields.
In March 2020, he was appointed Head of Sales and joined the Executive Committee.
