Penny de Kuijper

Office Manager

That everything within the office runs smoothly, we owe to our 'Ms. Planning': Penny! She is not only the first contact at Onesta (whether by telephone or face-to-face), but she also takes care of the planning and agendas of all colleagues. Is there an appointment that needs to be rescheduled last minute, or are we stuck in the printer with a paper emergency? Thanks to Penny, these problems are solved before you actually realize it. Add to that a good dose of service orientation, and you have penny's winning formula!
