The courage always to propose the most valid and stable solution for the medium/long term, even if it is not the simplest and most accommodating in the short term.

Paolo Zamberletti is appreciated for his competence and ability to provide original ideas (even when they are uncomfortable for the clients) that always look to achieving the best possible solution.

Paolo Zamberletti is a true team player, who combines his skills with the ability to team up, and with an approach that is never arrogant but always collaborative – it was a real pleasure from a human point of view to work with him, not something that I can always say about other professionals from other law firms!

Great availability and competence from Andrea Campana and his team.
