Minutes from the Chiasso border
Mendrisio is the historic and main office of Fidav. From here we coordinate our activity and closely support businesses in Mendrisiotto and across the whole canton.
The location, a few minutes from the Italian border, is no detail: it makes us the ideal reference for those who live and work between Italy and Switzerland — from cross-border workers to entrepreneurs looking at the Swiss market. It is a daily experience, not an occasional one: which is why we can anticipate problems, not just solve them.
