Jan Egbert Krikken - Digital Marketing Manager Geomares Marketing

Jan Egbert Krikken

Always surveying for new opportunities in the ever-changing online landscape. Over the years Jan Egbert has gained much experience in online publishing, analytics, UX design and web development. He describes himself as a creative technical centipede. A typical Dutch way of saying he is a generalist; a jack of all trades in the field of online communication and maybe even a little beyond. Your best chances of meeting Jan Egbert in his spare time are while running a marathon, climbing a wall, enjoying a concert, hiking a Norwegian mountain or sailing a Frisian lake. This may all sound adventurous and sportsmanlike, it is however mostly hypothetical, since he is the loving father of four little children. ;)
