JUMO Management Team

A reliable partner for custom-made solutions

We have been an owner-operated family business since its establishment in 1948. Chief Executive Officers and General Partners Bernhard Juchheim and his son Michael manage JUMO together with Chief Executive Officer Dimitrios Charisiadis. They continue what has been important since its establishment by Moritz Juchheim: people, values, and innovations. This culture is caried through in the Dutch branch that was founded in 1976. Director Steven de Graaf, together with Dirk Kop and Marco Buurman, manages this location.

Marco Buurman, Steven de Graaf and Dirk Kop run the Dutch establishment together.

Since its foundation, JUMO has been aware that a good personell policy and innovative solutions for customers are the most important building blocks for a succesful company. Within our globally active family business, team spirit plays an important role, in which we encourage our employees to develop in a safe and pleasant working environment. Our high-quality innovative products are of high quality and are produced in a sustainable and responsible manner.
