Assistant Controller

'Success is liking yourself, liking What you do and liking How you do it.'

As Assistant Controller at JBR, I have a versatile responsible position. Supporting with reports and adequately following up on appointments is my thing. The various disciplines require a flexible attitude, control I like to do and above all perfect.

Surrounded by nice driven colleagues, the freedom and responsibility I have within the organization makes it the ideal fit for me.
