Kees Quak (1956) has been affiliated with DEMO as a member of the Advisory Board since 2018. Mr. Quak is by origine a fiscal specialist. After starting his career at the Tax Administration, he founded his own consultancy firm with a partner, initially mainly tax-oriented but gradually rolled out into an office that focused on business advice in the broadest sense of the word. His financial expertise and empathetic customer approach made Mr. Quak an in-demand adviser. As a result, the resulting high workload became increasingly difficult to combine with the care of his growing disabled son Rens, which is why he chose to integrate his consultancy firm into Alfa accountants' office in Naaldwijk in 2001. To this day, Mr. Quak provides his services - sometimes from his broad financial expertise - as an experienced senior partner.
