Being always aware that clients require cost and price efficiency as well as high-quality, agile, effective solutions, and with the mindset that we must operate and grow in a way that is healthy, sustainable, mindful, and consistent with our values, we adopt the most modern and innovative management methods to support our constant pursuit of improvement.

The best way to do this is with people who meet high technical standards, and are diverse, empathic, and so motivated that not only do they execute the management plan, but they also help build it. Therefore, people are one of the pillars of our management. Hence, monitoring performance, making training programs available, and caring for employees’ physical and mental health are fundamental practices, as is building an integrated work environment where we value collaboration and shared knowledge.

We want to execute our new management program with persistence and discipline, and we believe ethics and principles are the basis of any relationship – and relationships happen to be one of our values. Therefore, governance is fundamental to ensuring that principles will be respected throughout the journey and thus guaranteeing the trust of the firm’s interest groups such as partners, employees, clients, vendors, and society at large.

That is why our partners meet frequently and regularly, as do our committees, to address, propose, approve, and monitor the implementation of policies, procedures, processes, and various other matters, always prizing a diversity of perspectives.

Probono / Projetos Sociais

Pro Bono/ Social Projects

We consider it our duty to contribute to society and we do that in various ways, one of which is pro bono work.

Together with our commercial partner DLA Piper, we advise several organizations oriented towards various issues, all with a common goal: transforming our world into a better place.

All our pro bono work is done by volunteers from the CMA team, who are also passionate about the goal of being able to contribute to Brazilian society.


At CMA, we believe our clients are our business partners and we must constantly improve to better serve them. We continuously invest in various forms of training, with secondments being one of them.

We are very proud to be able to provide our lawyers with the opportunity to undergo secondments at various DLA Piper offices, in different countries and continents. In addition to providing professional learning, a secondment is an enriching personal experience which will make a mark on their careers. "



"Our recognition is s result of the CMA team of specialists’ daily contributions to solving our clients’ challenges.

To us, nothing is more important than the relationship and the excellence we offer to our clients. This is embedded in our values. And that is why we have adopted the NPS (Net Promoter Score) methodology as a process in which we are constantly evaluated by our clients. Our most recent score (2021) was 89, which is considered to be within the range of excellence – the highest level under the methodology. In addition, we participate in the most important legal rankings and are often compared with the best law firms in evaluations made by major organizations using the opinions of professionals from the world’s largest companies as a criterion. We have obtained significant recognitions, and the specialized work done by the CMA team has made us into a reference firm. "
