2 September 2025
Effective 1 November 2025, Annemarie Maarse will be appointed Chief Operational Officer (COO) and will join the Bouwinvest Board of Directors. This will complete the three-member Board of Directors, which also includes Mark Siezen, Chief Executive Officer (CEO), and Henk-Dirk de Haan, Chief Financial & Risk Officer (CFRO).
In her new role, Annemarie Maarse will be responsible for Bouwinvest’s operational performance, with a strong focus on investment results, client satisfaction and operational efficiency. She will head the Dutch and International Investments business units and the Client Services and Business Technology departments.
Wendy Verschoor, the Chair of Bouwinvest’s Supervisory Board, says: “We are delighted to have filled the new COO position with an internal candidate. Annemarie knows the organisation and strategy and will therefore guarantee continuity. I know Annemarie as someone who not only has an eye for returns, satisfied clients and efficient processes, but also for the people and culture that make Bouwinvest what it is. I am therefore convinced that Bouwinvest will be able to continue to build on what is a solid foundation.”
Annemarie Maarse is currently Head of Asset Management at Bouwinvest. In this position, she is responsible for the evaluation of the existing asset management organisation, which has led to strategic partnership agreements with three property managers for Bouwinvest’s Residential, Healthcare, Retail, Office and Hotel funds. Bouwinvest will now start the search for a successor to her current position. Prior to joining Bouwinvest, Annemarie was Director of Asset Management at Achmea Real Estate and Head of Asset Management Residential at Altera Vastgoed.
