Guillaume-Hadrien Marion
President
I set up Ceres Capital Advisory with the ambition of offering an approach that combines high-quality technical expertise, a range of complementary and personalised services and strong values based on people.
Based on that I wanted to build a solid, diversified network of experts and specialists, with a broad but clearly identified scope, so that we would be able to adapt to any situation, any project and any request.
With a wealth of experience gained in investment funds, consultancies and major international groups, I have acquired extensive know-how that enables me to quickly understand the specific needs of each case, the ambitions expressed and the means to achieve them.
In addition to this career path, my various personal commitments within the French Red Cross and as a reserve officer in the French Navy have convinced me of the need to place these values at the heart of my professional approach.
