Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- I believe that the team's main characteristic is human: a trusted advisor. You can rely on them, and you can trust that they will try to do their best to clarify an event in an ethics and compliance investigation, for example.
- Luciano Souza was always available and loyal. He put all the resources needed to clarify issues.
- Cescon worked with us on compliance and investigations. An extremely capable and attentive firm, setting itself apart from many in the market.
- Esther Flesch, who always demonstrates excellent leadership, knowledge, and strategy in dealing with complex issues related to compliance and investigations.
- Esther Flesch is the partner of the firm who truly understands the subject and stands out in the area! I do not know the other professionals.
- When choosing a law firm to provide services, we should consider not only objective criteria—knowledge of the subject matter, reliability of delivery—but also subjective criteria, such as whether that firm understands the nuances of my business/company. Cescon does this with excellence. It provides services according to the client's risk appetite, conveying market insights and best practices in the judicial contexts in which you operate.
