The company has been managed for six generations by the family members and offspring of the founder and namesake Wilhelm Karrenberg. In 1989, following the sudden death of his father-in-law, Friedrich Karrenberg, Wolfgang K. Schlieper was appointed as the managing partner. His son, Robert Schlieper, will carry on the family tradition in his wake.
Who we are, what we do and what drives us. That is WILKA!
