John Koster has been a partner at Holland Consulting Group since 1997.

He studied business economics and philosophy of science before gaining his doctorate at the age of 29. He was later appointed director of the Ribes Research Institute at Eramus University.

At the beginning of the 1990s, he realised that consultancy was his calling and focused on this profession full-time. However, he still has affection for academia, as demonstrated by the many publications and part-time lectureships he conducts for various universities. In 2005, John was appointed professor of marketing at Nyenrode Business University, concentrating on the organisation and implementation of marketing. His main focus is on the cutting edge of strategy, sales and marketing, particularly within B2B environments and for professional service providers. However, non-profit institutions also regularly enlist his help. John is extremely interested in post-merger integration ("that's when everything really comes together") and gives lectures in this subject at Rotterdam School of Management.

In 2006, he succeeded Prof. Willem Vrakking as chairman and management partner of Holland Consulting Group. In his free time, John is actively involved in the cultural sector as a director/supervisor.
