The history of Studio Legale Marensi is three generations deep. Lawyer Placido Marensi began successfully practising law in 1888, focused on the constitutional and corporate aspects of legal defence. He held important positions in the Municipality of Milan, obtaining prestigious public recognition.

As a result of the important teachings from his father, the lawyer Bruno Marensi practised the law profession in an exemplary manner, respected by judges and his peers. He received the gold medal from the Council of the Law Society of Milan. His son, the lawyer Paolo Marensi, along with the colleagues that work with him at the law firm, is continuing on the prestigious path for which his predecessors paved the way.
