Our management team
A strong company needs strong management – and Sievert has always had that since it was founded in 1919. Even today, the founding family, Sievert, is still represented: Prof. Dr. Hans-Wolf Sievert, grandson of company founder Carl Fliege, is Honorary Chair of the Supervisory Board. The corporate form of the company was changed in May 2020 and the company is now Sievert SE, a change that makes our international outlook even clearer.
