The Dutch National Institute for Public Health and the Environment (RIVM) is the premier center of public health expertise in The Netherlands. Under the leadership of Director-General Marc Sprenger, the Institute has grown from roots in the Central Laboratory for Public Health in the early 1900s to its current status as a national and regional center of excellence with 30 units, more than 1,500 employees, and an international reach stretching far beyond its Bilthoven campus.
