For 15 years, the sales management of Humanchemie GmbH has been entrusted to Dr. Christian Beuermann (Direct Customers + Export) and Dr. Katja Günther-Schade (Key Accounts + Marketing). This arrangement has enabled both to remain active in R&D, Purchasing, and Quality Management. Initially, it was questioned whether the divergent interests of research and sales could be reconciled. However, experience demonstrates that precisely this combination fosters continuous, practice-oriented development of our products.
