I had the pleasure of meeting Alexandre Sion in a corporate environment. In the end, I gained an excellent colleague and a rare professional! Alexandre Sion, as well as being an excellent person, is highly qualified and up-to-date, interested, ethical and always in constant development. Working in my field (mining and energy) with the support I received from him has always given me the confidence to move forward with the certainty of achieving the challenging goals we have always had.

Alexandre Sion is an excellent professional, with in-depth knowledge of the environmental area that is critical to the proper development of projects. His help was fundamental when we worked together on a large and challenging project in Minas Gerais.

In our professional journey, we have the opportunity to meet people who make a difference, and we have the pleasure of learning from them and recognizing their competencies. Alexandre SION is one of those people, and on several occasions I witnessed his energy and dedication in solving problems, as well as his respect for others by listening and guiding. In the Minas Rio project, SION’s leadership, coordination of the legal team, and focus on results were decisive for the progress of the environmental licensing process and several procedures of this major enterprise.
