Studied graphic design at the IVKNO, now called the Rietveld Academy in Amsterdam. Started as a freelance designer working for a large Dutch publishing house. Joined (1977) a small design partnership that grew out to be one of the largest design studios in the Netherlands after merging (1987) with an established group of interior architects and industrial designers. Became director of professional development of the new partnership, BRS Premsela Vonk. Worked as design principal in many major and comprehensive corporate design and/or signage commissions for Dutch governmental bodies and multinational companies. The partnership, nicknamed in the Netherlands ‘the Ministry of Design’, made a major contribution to the Dutch government’s perspective on (graphic) design, which is still surprisingly unparalleled in other countries. He invented and developed a modular sign panel system (mss 0.5) now produced under licence in various countries around the world.
