About me

Karen is passionate that the key to competitive advantage is rooted in deep consumer insight. Her knowledge of consumer trends, continuous changes in technology which then influence and change consumer behaviour, are fundamental when looking to future-proof business. Karen began her media career in 1993 at CIA MediaNetwork (now known as MEC), working across a range of direct response accounts as a specialist direct response planner and buyer. Karen continued her career by joining Zenith Media in 1995 as a Senior Communications Planner working on the prestigious BT account. Karen was quickly head-hunted by The Media Business Group to take up the role of Media Manager.    In October 1999 Karen was promoted to the Board of Directors of the newly merged MediaCom and The Media Business Group Board. In January 2003, Karen moved from the Business Director role that she had held for so long to become the Marketing Director of MediaCom.  In 2008, Karen became MediaCom’s Chief Operations Officer for EMEA. Priority markets included Russia, Turkey, France, Spain, Portugal, Poland, Czech Republic and South Africa. After 3 years strengthening the EMEA network, during which time MediaCom moved from the 5 th to 3 rd largest EMEA network media agency, Karen was promoted to CEO of the UK Office in January 2011, running over £1.3bn of media billings and over 1,100 people.  MediaCom UK is the largest media agency in the UK with a range of diverse clients, such as Sky, Tesco, GSK, Coca Cola, CRUK, DFS, NBC Universal and Mars.  MediaCom is a truly UK national agency with offices in London, Manchester, Birmingham, Leeds, Edinburgh and Dublin. During Karen’s tenure as CEO the UK business won over £790 million of new business. (2011 -2015 inclusive). In January 2016 after serving as CEO for 5 years, Karen was promoted to Chairwoman of MediaCom UK & Ireland and is closely linked with clients such as Tesco, Allianz, Coca-Cola and Sky. In her new role as Chairwoman, one of Karen’s many focuses is to support the continued growth and evolution of the regional UK offices which totals 350 staff and has regional combined billings of £385 million.
