Associate Partners

Diederik van den Biggelaar and Janco Duvekot know what it’s like to break a sweat. Diederik explains. ‘A personal approach is self-evident to us, precisely because we have years of experience, including as entrepreneurs. We know what responsibility means, the strains upon a businessperson. So we can quickly sense what our client is looking for.’
