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 can most certainly recommend Alexandre as a highly skilled and efficient lawyer who has deep knowledge in international commercial law and especially environmental law issues. As a person Alexandre is very outgoing and social with good teamwork skills.

Highly focused and extremely dedicated, ALexandre is certainly one of the best in-house lawyers I have ever met. I strongly recommend him in the environmental law field.

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!

We have had the great honor of counting on the legal support of Sion Advogados in matters of Mining and Environmental Law. The commitment, dedication and competence with which the team deals with the issues is outstanding, and they always come up with innovative and feasible proposals for dealing with the issues they are asked to deal with. I recommend the services provided by this team.

Thank you for all these years together on this journey!

We hired Sion Advogados for an extremely sensitive issue, and with a great deal of skill and knowledge in the environmental mining sector, the result was just the start of a great partnership. Alexandre is a professional who gets involved in the issues together with his team, and has a vision of the company that is very important for developing excellent results. As well as extreme technical ability, he has a great interpersonal relationship that facilitates communication and support for companies.

I had the pleasure of getting to know Alexandre’s excellent work […] when his company provided relevant legal support in the administration of contracts with international companies, […] he showed vast knowledge of international law, ethics and fidelity, competence and excellent quality in his defenses.

During our years studying together, Sion was one of the most intelligent, prepared and dedicated student, if not the best one. I was really glad to know that he has been approved in the bar exam with great grades and that he started to work in respectful companies for the last years. I can easily say that whoever decided to be represented by him, will be in very good hands.

Sion is a competent and multifaceted professional. As a postdoctoral fellow at the University of Salamanca, Spain, he has proven to be an innovative and dedicated researcher; as a teacher, I had the opportunity to be his student on the Environmental Law course, he has a great ability to transmit knowledge, to capture everyone’s attention with a dynamic and participatory class and to foster the creation of a network of professionals among his students.

In addition to great technical competence, zeal and punctuality, I would like to draw attention to a very important characteristic of the firm, which is that it knows how to reconcile and mitigate legal risks with the business interests involved in the most complex claims submitted to it.

I had a pleasure to have contact with Alexandre, as a client when we’re had worked on the same company, whoose is a very competent and skillful professional, principally on matter of process and international law respecting commercial agreements.

In my opinion, Alexandre is one of the most complete Brazilian lawyers in the areas of mining and environmental law. I have had the opportunity to rely on his experience in these areas and therefore strongly recommend both him and his firm.

Alex is a natural leader. Not only did he stand out among the students while we were at UC Davis, but also encouraged and supported everyone else to be excellent. I would strongly recommend him and he is in the top of my list for legal advice in Brazil.
