Our History

In the heart of Munich since 1932

Our law office for the corporate and private-client affairs of

small and medium-sized enterprises was set up in 1932 by lawyer Dr. Waldemar Kiessling in the heart of Munich.


In 1927/28, Dr. Kiessling had already spent a year of his legal clerkship at a law office in New York "with the approval of the Bavarian Ministry of Justice". In April 1932 he went on to open the office at Residenzstraße 18 opposite the Munich Opera House, where it remained until February 1997, when it relocated to the present address at Maximilianstraße 35 due to lack of space.


In 1967, Dr. Georg Wirsing joined the firm as a young associate. He continued the business unchanged, also after the death of Dr. Kiessling in 1977,focusing successfully on the sphere of private clients, until he himself passed away in 2018.


In 1985 the firm welcomed Dr. Claus S. Hass, who shaped the business with major clients from film and TV production as well as private clients.


In 1995 the business was expanded to include the financial market. Dr. Michael Zoller, who became a name partner in 2013, established the office as one of the go-to addresses for financial service providers involved in capital market law disputes and is the author of the standard reference work "Die Haftung bei Kapitalanlagen" [Liability for Capital Investments]. He and his team operate throughout
