Company History

In 1970, in Stuttgart, Gerhard Drees founded a small engineering company. At that time, he and his co-founder, Hans Sommer, could never have imagined that their three-person team would grow over time into an international company with more than 6,000 employees. To this day, Drees & Sommer continues to be characterized by the ability to innovate and to "think outside the box".
