With the growing globalisation of public affairs, Catherine anticipated the demand for on-the-spot advice on EU affairs to US corporations and trade associations when she opened an office in Washington D.C in September 2001 which is now Interel Consulting Inc.

As Chairman of Interel European Affairs her vision of effective public affairs is to provide experienced and intellectually–driven advice, intelligence and lobbying services on EU legislative and regulatory issues to valued clients. Catherine provides strategic advice on EU policy issues and practices to a broad range of clients in sectors as diverse as mining, automobile, media and financial services. Her extensive experience of EU affairs and her network of contacts at the highest level in Brussels has led several high-profile multinationals to seek her advice on the effective restructuring of their global public affairs activities and to entrust her with confidential and targeted opinion research about their companies amongst senior and influential policy makers.

 As Group Practice Leader of Public Affairs in the Interel Group, Catherine is broadening the Interel International Network of Affiliates to provide clients with a team of expert advisors at national and European and international level.
