Our organisation

Our organisation is flexible so that we can respond quickly to new tasks and developments in society. We do this with a workforce of some 4,000 experienced staff. We can incorporate new implementing tasks into our organisation and adapt where necessary to ensure the best possible service.

The Board is accountable to the Minister of Social Affairs and Employment for our performance. Meet the members of the Board.

Mr R. Paas


Ms R. van den Broek


Ms M. Vogt-Claessens


Ms S.M.J.G. Gesthuizen


Ms Keklik Yucel


The Client Council of the Sociale Verzekeringsbank (SVB) is made up of SVB clients and representatives of relevant interest groups, and provides the board of directors with suggestions and advice both on its own initiative and on request. For example, it can advise on whether the rules for clients are clear enough, or whether the information we give is getting through to the right people.

As a discussion partner for the Board of Directors, the Client Council helps to improve the quality of our services, for example by making suggestions and passing on client reactions and complaints. The Client Council meets 4 to 6 times a year. There are also a number of working groups with varying participants that meet during the year to prepare recommendations.

It is not the task of the Client Council to provide assistance or mediation in the case of complaints. If you have a complaint:
