GenDx supports ‘Mens Sana in Corpore Sano’: all employees get access to the facilities of Sportcentrum Olympos.

Sportcentrum Olympos and GenDx have signed an agreement, which implies that all GenDx employees are granted access to the sport facilities of Olympos. The costs of the so called all-in sports card ‘OlymPas’ for one year will fully be borne by GenDx. The agreement fits in the mission of Olympos to stimulate healthier life at Utrecht Science Park (USP). Several agreements with other organizations at the USP have already been set. This is the first agreement wherein the employer will pay for all associated costs.



Wietse Mulder, CEO at GenDx, commented: “We are happy that we have signed this agreement and can give all our employees access to the nice sport facilities of Olympos. It underlines one of our corporate values, which is supporting employees’ development and job satisfaction”.


Cees Verhoef, Managing Director at Olympos added: “We strive to have excellent sport facilities for students and employees of HU, Utrecht University, and other organization located at USP. We are convinced that regular exercise has a positive effect on both the joy and results of a working day. We notice that employees who schedule their working day including a moment of exercise that clears the mind, are more productive and energetic after. Also at the end of the day, if they leave a bit later, they’ll avoid the evening rush hour and once at home they’ll have more time for their family life. That provides a better life/work balance and less stress. We are looking forward to this collaboration with GenDx and we encourage other USP organizations to take such an initiative as well and above all we are looking forward to how the GenDx employees themselves will look at this initiative after a year!”.
