The founders of the Diethelm and Keller companies started their businesses in the late 1860s, trading products between Europe and Asia. Over time, descendants of the founding families expanded the trading business to take in marketing, logistics and related services, while also diversifying into industrial activities and other segments.
Today, the Diethelm Keller Group consists of five operating units, plus the divisions Diethelm Keller Real Estate and Shareholder Services as well as participations in DKSH Holding Ltd. and Bergos Ltd. All subsidiaries hold strong positions within their respective fields and operate with a high degree of entrepreneurial autonomy.
At the end of 2023, the Diethelm Keller Group employed more than 2,000 people in 17 countries.
