About us
Our History
The firm was founded in 2004, with the union of colleagues from the Law School of PUC-SP, and since 2008, Celso Mannrich and Breno Vasconcelos have been at the head of the company’s administration.
In 2012, due to the growing demand of our customers, we strengthened our operations in Minas Gerais, with the opening of an office in Uberaba, in partnership with Gilberto Vasconcelos.
The year 2013 marked our history with the entrance of Professor Nelson Mannrich, who expanded the wingspan of the labor area, today coordinated by him together with Celso Mannrich, Fábio Lima and Roberto Rossetti.
In 2018, with the entry of Marco Sabino, we renewed the dispute resolution area and inaugurated media and internet practice.
Alongside new leaders such as Thais Veiga Shingai (tax) and Alessandra Boskovic (labor), and highly dedicated professionals, all have the mission to look after the values of the office.
Every step taken in this story, right or wrong, helped shape today’s office: open, ethical, participatory and willing to make a difference.
