The business's history stretches back over 60 years, to the single-partner auditing practice set up by the firm's founder and namesake Dr Elke Dornbach Sr in Koblenz in 1954. The addition of further partners led to the firm's creation in 1970.

The outsourcing of the areas of legal and management consultancy, as well as geographical expansion into the new federal states, into the business centres of the Rhine-Main area (Frankfurt, Wiesbaden, Mainz, Darmstadt...) and to Munich, has created the present Dornbach structure, with 52 partners and over 450 employees at 21 locations.

According to the 2015 Lünendonk® Study, we can count ourselves among the 15 leading accountancy firms and the top ten owner-managed professional enterprises in Germany.
