Meet Our Experts

Since 2016 I'm Head of Research & Consultancy at Colliers International Netherlands. Before the merger with WPM Groep, I was responsible for Research and Consultancy of this real estate management organization. Within Colliers International Research & Consultancy, I focus on realizing the internal and external goals we have set in our strategy, together with the development of the Research & Consultancy team in order to follow our mission: “To continuously enhance Colliers thought leadership by delivering fact based insights, innovative solutions and disruptive perspectives”. In addition, I continuously seek for business development opportunities with all teams of Colliers International Netherlands, cooperate with the Colliers EMEA Research-team, enhance knowledge development and provide consultancy services to external clients. I work for investors, (local) governments, project developers, retailers and law firms, advising them on both a strategic-tactic and operational level. My expertise lies in the field of commercial real estate and specifically retail.

Before Colliers International and WPM Groep, I used to work for ECORYS for more than seven years, the last four years as senior consultant retail. Ecorys is a consultancy firm focusing on spatial and economic development. In this period I worked for many different clients, with a wide collection of projects: feasibility studies, portfolio analysis, second opinions, retail visions, concept development, market analysis, impact assessments, reviews and location studies for retailers. In 2011 I was project leader of the Randstad Koopstromenonderzoek (spatial consumer expenditure) on behalf of the province of Utrecht, Noord-Holland, Zuid-Holland and 50 municipalities.
