To mark its 75th anniversary, Janson is introducing an anniversary label that will accompany its visual identity throughout the year. It highlights the firm’s experience, continuity and ability to stay in tune with the times.
In 1950, a pioneering idea took shape: the creation of Belgium’s first structured law firm. Since then, Janson has evolved with the legal, economic and societal landscape, while keeping the law at the service of those who practise it.
Today, with nearly 100 lawyers and offices in Brussels, Ghent and Mons, the firm advises a wide range of clients in Belgium and abroad.
