After obtaining a banking diploma, Hans-Hermann read law and economics in Münster (PhD), Düsseldorf and Sydney (LL.M.). Besides this, he underwent Executive Training in Law Firm Leadership at Harvard Law School. He was educated in the US and worked for multinational corporations in Bangkok, Johannesburg and Singapore before joining a leading international law firm in 1999.

Hans-Hermann joined Simmons & Simmons in Düsseldorf as a partner in 2002. He became head of the Düsseldorf and Frankfurt offices in 2006 and has led the firm's global International Disputes Practice Group since 2008. The JUVE Handbook 2013/2014 quotes clients who describe his work as being of high quality. Furthermore, he is recommended as a leading practitioner in each of the current editions of Chambers (where he is described as “extremely bright”), Legal 500 and Who is Who Legal. Chambers Global cites clients who describe Hans-Hermann as "a consummate professional who explains difficult legal issues in plain English, which is remarkable given that it is not his first language. He is engaging, straightforward and extremely pleasant to work with". The leading German weekly magazine WirtschaftsWoche ranked him as one of Germany’s top practitioners for compliance.

He publishes frequently in the areas of employment and criminal law and lectures on corporate restructuring at the European Business School, Oestrich Winkel. By invitation of the United Nations, Hans-Hermann advised the government of the Palestinian administrated regions on anti-corruption legislation and acted as a trainer for the legal authorities in 2013. In 2015, members of the German parliament consulted him as a legal expert on the draft legislation against corruption in the health sector.
