About US

The Jung + Theuergarten engineering company was founded in 2019 by Rolf Jung and Olaf Theuergarten in Siegen. The office emerged from the merger of the planning office founded by Rolf Jung in 2004 and the engineering office founded by Olaf Theuergarten in 2006. 

Our office stands for reliability and trusting cooperation. With the necessary skills, we align our actions to the needs of our customers and the joint project. A high level of transparency and open dealings with each other also form the basis for a successful project. 

Motivated and qualified employees are the foundation of our success and the driving force for innovative performance and goal-oriented action. We currently employ three architects, three civil engineers, one office worker and two freelancers.
