The Bielefeld office dates back to a firm founded in July 1895 by later-to-be Counselor of Justice Dr. Otto Cramer. In the early 1950s, Dr. Cramer‘s office merged with a firm founded in 1925 by attorney and notary Dr. Rudolf Nierhoff, who headed up the ever growing practice until the 1980s.

The office primarily focuses on advising and representing midsize businesses in the areas of commercial and corporate law, labor law, intellectual property rights, IT law, construction and public procurement law, banking law, insurance law, commercial tenancy law, as well as medical law. It also features a comprehensive notary office.

The Detmold office evolved from the firm of Deppe, Dröge & Partner, which was founded in 1973. At the time, this was the first merger of accountants and attorneys in East Westphalia/Lippe. From the beginning, the focus of the attorneys working at the Detmold office was on advising midsize, owner-managed companies in all areas of commercial law with a clear focus on corporate and tax law.
