Our roots go back to 1939 when René Kartheiser founded the FIDUCIAIRE KARTHEISER as a sole proprietorship. Over the years and through mergers, it has become FIDUCIAIRE BENOY KARTHEISER, also known as FBK, making us the oldest certified accountant company in the Grand Duchy of Luxembourg.
2018 was marked by the moving from the route d'Arlon to 24, rue Saint Mathieu L-2138 Luxembourg - Pfaffenthal district of Luxembourg City.
