The Heppie association is a nationwide organisation of volunteers that organises supervised group holidays, relief weekends and parent/child holidays. On an annual basis, over 400 volunteers offer more than 1,200 children the opportunity to recuperate for a bit and experience some positive moments. This is done in various locations in the Netherlands.  The help that FEMI offers in the building of the holiday hotel in Mierlo is in line with what also forms the core business of the Hooge Raedt Group: holiday parks and hotels.
