Building on more than a decade of experience as an attorney, both in and out of court, Jan combines a profound understanding of Dutch and EU regulations with a pragmatic approach.

Aside from an extensive track record in transactions, he advises and very regularly litigates on behalf of project developers, (multinational) industrials, (institutional) investors, as well (local) governments and public transport companies. Over the years, Jan has dealt with matters before a host of competent authorities ranging from municipal and provincial executives to national bodies such as the Dutch Human Environment and Transport Inspectorate and the Authority for Consumers and Markets. His broad experience allows Jan to see past the mere regulatory side of a matter, translating legal assesments into pragmatic, commercially strategic, and actionable advice.
