  • In 2010 I started secondment agency Or-Quest for construction, infrastructure and industry. My goal was clear: to be one of the top three best secondments from the Northern Netherlands. Several entrepreneurial awards, including the FD Gouden Gazelle Award, confirmed that my strategy is working. Our plans for the future are ambitious and together with the offices of TSG Group we can let even more professionals experience happiness at work.
