Three strong brands under one roof

The Thommen Group is made up of three separate brands, all firmly established on the market. Whilst each operates in its own name, they ideally complement one another, thus allowing the Thommen Group to consolidate its market position. And looking to the future, its broad geographical coverage will also enable it to offer optimum service to its customers.
