A great joy for our young team and the whole company: this year, four apprentices – in the fields of multi-skilled mechanics, production mechanics, and business administration – have successfully completed their apprenticeships! A big thank you to all four of you for your fantastic work! And, of course, we are particularly delighted that the two apprentices with a background in mechanics have decided to stay with us and to take up permanent positions at DUAP. To the other two, we wish a successful career start outside of DUAP.

Heribert Geisser Square at the heart of our company
November 25, 2025: “No one can do it alone, only the community can do it.” With these words, our patron, Heribert Geisser, who is over 90 years old, unveiled the sign dedicated to him yesterday on his 40th anniversary with the company. And DUAP, which he saved 40 years ago, continues to develop every day, thanks to the vision of our patron also, Heribert Geisser.
