The core value of Eight Advisory that defines me the most


In each project I have led, I have endeavoured to take the viewpoint from entrepreneurs, managers and their shareholders, in order to design and implement solutions adapted to both the issues encountered, the management’s vision and the firm’s culture.

I also systematically ensure, in these transformations, that teams are onboarded and that ambitious and actionable plans are designed, to bring concrete results.
