Headquarters Germany


The parent company and the main administration of Rosenberger is in Fridolfing in the southeast of Germany in the middle of the Upper Bavarian foothills. From the locksmith's shop founded by Hans Rosenberger senior in 1958, the internationally operating Rosenberger Group developed over the course of six decades. Together with its partner companies, it is now one of the world's leading providers in the areas of high frequency, high voltage and fiber optic technology.

This makes Rosenberger one of the largest and most attractive employers in the region with the company still being family-owned.

Geographical roots with tradition

Fridolfing is located in the scenic “Rupertiwinkel” in close proximity to the historic cities of Burghausen, Laufen and Salzburg. Surrounded by the Chiemgau, Berchtesgaden and Salzburg Alps, the location between the Salzach River and the Waginger lake offers a high level of recreational value and, thanks to the strong regional economy, ensures an excellent quality of life.

Rosenberger has always been deeply rooted in the Bavarian landscape and culture and, despite increasing internationalization, is fully committed to the Fridolfing location - based on the successful “laptop and leather pants” model.
