Office Cologne

The origin of the location in cologne goes back to 1936, as Mr. Rudolf Verhülsdonk founded an auditing practice. This was the basis for the successful expansion with later added locations in Berlin, Chemnitz, Dresden, Düsseldorf, Iserlohn and Koblenz, which initially have combined under a joined company Verhülsdonk & Partner GmbH. Now, Verhülsdonk & Partner GmbH merged with further added auditing companies to RSM GmbH and is internationally closely related within the RSM Network.
