Inge got her LLM degree at Erasmus University in Rotterdam in 1982, and continued to specialize in Tax Law at Leiden University and the Dutch Tax Administration. Between1989 and 2002, she consulted employers on international taxes and global workforce topics.
In 2002, she created the Expatise™ brand and formula and fully dedicated herself to the professionalization of expatriate management, both from an employer's and employee's perspective, in a corporate (interim) role and advisory role to many profit and non-profit multinational companies, as well as national government organizations.
Since 2007, she has chaired the Dutch Expatriation Foundation (DEF), a collaborative network platform and interest organization for international employers in the Netherlands.
In 2010, the DEF founded the Expatise Center in close collaboration with these employers and in 2011 the Expatise Academy. Since its inception, Inge has been its chairwoman and CEO.
