CGM is a unique firm with uniquely talented practitioners. The named partners and several of the others are exceptionally bright and responsive. Their performance level is up to the best of the largest firms, with even greater attention to the individual needs of clients. They work hard and produce the same results (or better) as their peers at firms that are reputed to be the best in Brazil.

I find Rene Gelman and Martim Machado both exceptionally bright, and I value their judgment on complicated matters. Both are able to zero in on the issues, put them in the appropriate perspective, and deliver answers that can be relied upon. And they are always responsive, and clients can always count on them. And their rates, staffing levels and efficiency are exceptional.

Excellent professionals, assertive, objective, in-depth technical knowledge and quick responses.

Adriano Chaves and Camila Magami are recommended.

Personal attention and great service.

CGM was founded by an experienced group of partners who have been working together for more than two decades, and were joined by other partners coming from reputable law firms.

CGM enjoys strong client and market recognition as acknowledged in important international publications and rankings. The firm’s service model focuses on solving its clients’ issues in a responsive, efficient and business-oriented manner, combining technical expertise and creativity.

With a team of professionals graduated from reputable Brazilian law schools, many of the firm’s lawyers have also obtained Master’s degrees and other qualifications abroad, and have worked outside of Brazil.

CGM has a tight-knit network of partnerships, which allows it to provide services throughout Brazil and coordinate multijurisdictional projects in Latin America. The team works at a very fast pace and has in-depth knowledge of the law and business environment of the region.

CGM positions itself as a “client-service firm”, which means it is prepared to assist its clients from the most sophisticated transactions to the management of their daily legal routine. CGM is keen on spotting issues but equally committed to addressing them. The firm’s team eagerly pursues solutions to help clients do business and achieve their goals. In addition, the firm’s professionals’ long-term experience working with international clients results in the ability to explain the Brazilian legal system to foreigners in a very practical way and in being sensitive to the cultural differences of doing business in Brazil and elsewhere.

CGM assists domestic and foreign clients from various industries, with strong expertise in agribusiness, automotive, banking, chemicals, construction, defence, e-commerce, energy, healthcare, heavy industry, hospitality and leisure, information technology, infrastructure, real estate, insurance, logistics, pharmaceutical, medical, professional and regulated services, retail, wholesale and transportation.
