Good day Christina! I am not sure how you mean your question exactly, but as far as I know, Mr Rik Eijsink is the head of the International Business School. If you have any issues or want to contact someone for assistance, you can either contact the International Office (internationaloffice@saxion.nl ) or the IBS service point (info.enschede.ibs@saxion.nl ).
I hope this helps and I did not totally misunderstand your question. If so, please feel free to ask again!
