In 1968, recently graduated attorney Hamilton de Oliveira, from Campinas, São Paulo, decided to open his own law office. This new endeavor was focused on Real Estate Law and Civil Contractual Law, thanks to Oliveira’s experience at the Campinas City Hall and friends of his who worked with civil construction. But it would not take long for the office’s areas of specialty to expand. It would eventually provide services in Family Law, headed by his wife, attorney Gitla Gindler de Oliveira from Bauru, São Paulo.

The venture showed consistent growth, which required its physical facilities to expand accordingly. In 1979, the offices moved from a tiny set of rooms at Edíficio Dom Nery to the then newly inaugurated business complex Edifício Cruz Alta. The venture would move once again in 1996 to what is now its current address, at Centro Empresarial Carmo in downtown Campinas.
