Logo-50esimo-engWE ARE THE HYSTORY

Apen Group has celebrated the 50th anniversary from its foundation at the “Museo Storico Alfa Romeo”, where three floors full of history try to connect past, present and future.

The event highlighted the evolution of a family company where two pioneers partners, both bearing the same name and surname “ Angelo Rigamonti “, began their adventure in 1967, with courage and great enthusiasm.

Enthusiasm and dedication have always been totally imparted and shared by the rest of the family later involved in the company, by the staff and by all collaborators.

Happy anniversary Apen Group and the best wishes for a present
and a future into the excellence which may contribute to the apreciation
of the italian factories.
