Our Company


The d.s.f. GmbH was founded in 1977 by Mr. Dietrich Schentke under the name Dietrich Schentke GmbH in Frankfurt am Main. With increasing growth and due to personnel enlargements, the company moved to Neu-Isenburg in 1992.

Due to the expansion of the management in 2008 by Mr. Thomas Rützel, Dietrich Schentke GmbH was renamed to
d.s.f. GmbH

In March 2012, Mr. Dietrich Schentke retired from the company for reasons of age. Since then, Mr. Thomas Rützel is the sole owner and managing director.
