In a world that is constantly changing, challenges for our customers sometimes arise so quickly that the Drees & Sommer Group is unable to develop appropriate responses in a reasonable time. In such cases, Drees & Sommer expands its expertise through shareholdings. Affiliated companies make their expertise available to the Group, thus providing a timely solution to meeting customer requirements.

In keeping with our aspirations and philosophy, the companies involved are all leaders in their fields. We work together with them as equals. In this way, the affiliates not only complement our service portfolio in an ideal way. Like us, they also work with determination to ensure our customers’ success.
