Gezondheidscentrum (health care center) Brakkenstein provides health care to students in Nijmegen. They are located next to the campus and contain general practitioners, a pharmacy, dieticians and psychologists.
As a student you can easily apply here.
If you apply, make sure to mention you are from BeeVee. This is done by getting a special card form the board of BeeVee, and giving that to the receptonist when you first visit. This way you support the association at no extra cost, whilst providing health care for yourself!
