Freshly graduated from ESCP, Christian Lambert joined his father and brother in the family business at the time, Scierie Ardennaise.

After the arrival of his daughter Pauline in the company in 1998, they together decided to create PSD Aero on January 1, 2001, by splitting the two business units.
They both realized the development potential of the company in the aerospace industry and from that moment on, they focused on the development of PSD AERO.

The growth of PSD Aero and its position in the industry are recognized by aerospace players. The CEO's diplomatic skills and talent for financial arrangements have greatly contributed to this success and the training of his daughter Pauline.
