Fivers expands in Rome and strengthens administrative law practice with Sergio Fienga
"Fivers hires partner Sergio Fienga and his team to reinforce its administrative law practice, with a focus on energy and infrastructure."
Sergio Fienga brings thirty years of experience gained at leading law firms. He specialises in administrative law, particularly in the energy & infrastructure sectors, which are central to Fivers' development strategy. After a long professional career, he worked at the Pedersoli firm, where he opened and developed the Rome office, and subsequently continued at PedersoliGattai.
He is joined by his team: Marco Trevisan (counsel), Jaime Guiso Gallisai (senior associate), Francesca Perna (associate) and Alessandra Lonardo (junior associate). Their arrival significantly strengthens Fivers' administrative law group and expands the firm's ability to assist clients active in regulated markets, with a specific focus on the energy and infrastructure industries.
"We are pleased and enthusiastic about the arrival of Sergio and his team," commented Francesco Di Carlo, co-managing partner of Fivers, noting that the move helps complete the firm's offering and enhances an area that has become increasingly central in recent years. Sergio Fienga said the choice of Fivers reflects his desire to operate in an innovative context capable of interpreting the evolving role of the administrative lawyer in rapidly changing markets.
