You can read a historical description of the foundation in the March 2016 newsletter. You can download this under News, but it is in Dutch.
ProRomi is the Dutch "Mother" foundation of the ProRroma foundation in Romania. Both have their own board. ProRomi also had an active director, Sjaak Monster, until June 2016, when he resigned after many years of service.
From January 2018, the ProRomi NL board consists of Jeanet Hertsenberg, Eric Voogt and Louis Holtrust. Jeanet was recently followed up by Kees Pijp.
