Started as a civil engineer in 1984 I changed to marketing and advertising in the late 80's. Together with Rob Winkelman I owned a small advertising agency, HCW La Tour. Much learned there. In 1991 I joined Kontrast Kommunikatie, as account manager. In 1995 I switched to the advertisers position. First at Canon Europe (communication manager printers in Europe) and later at ING Bank. Canon was my introduction to Internet. In 1998 I joined Virtual Affairs, a fast growing internet agency. In June 2002 I started my own agency: Tij Communicatie & Content. In 2006 I opened an office in Amsterdam, Keizersgracht. In 2008 Bert Pinkster and I started Strohm Bedrijfsvoerders. In August 2011 I joined Ellen Groenveld who started Museumwebshops.nl.
