Alexandre Sion is a professional I have had the pleasure and privilege of working with. First, together at Vale and then as a direct report at MMX and Anglo American. Leadership and the ability to manage people and strategic projects are natural abilities. He is an excellent professional and a person of integrity in his values and convictions, with intense experience in the law.

Alexandre is an outstanding student. During the time we studied together in Davis, California, I could realize that he is very disciplined, organized and is always looking for opportunities to learn and share knowledged with his colleagues. I should also mention his extra class behavior – he was perceived as a leader, organizing activities and always being available to help and cooperate with his classmates.

I have had the satisfaction and privilege of consulting Alexandre and his firm for a number of years. In two different companies, we have faced some significant challenges and the mission has always been successfully accomplished. Alexandre is one of the few people who can brilliantly combine technical quality, a business partner profile, great relationships and the right amount of combativeness. He is a key strategic partner. Thank you for your partnership!
