In 1970, Gerhard Drees founds a small engineering firm in Stuttgart. He and co-founder Hans Sommer never dreamt that the three-person team would one day become a company operating internationally with more than 5,100 employees. Today, just as then, innovation and thinking differently continue to be the hallmarks of Drees & Sommer.

As entrepreneurs, employees are client-oriented, responsible, and make full use of their freedom to make decisions independently. Everyone who works on projects with them feels the special Drees & Sommer spirit.
