We have a plan - the same one for over 60 years. Over the past 60 years, social issues have changed but our driving forces have remained the same – entrepreneurial courage, our eagerness to make decisions and our fascination for progress and technology.

In 1958, civil engineer Willi Schüßler laid the foundation for the present Schüßler-Plan group of companies in Dusseldorf. He started his own company at the age of 30 on 23 August, giving himself what in effect was the birthday present of his life. In the meantime, the family-owned company of Schüßler-Plan is in its third generation. The new partners, Christina Zimmermann, Paula Wagenbach and Nina Baden-Wassmann, will ensure that the company remains in family hands in future. The three partners took over the shares of their fathers Norbert Schüßler, Bernd Wagenbach and Wolfgang Wassmann in 2018.
