At GSK, she led profile campaigns for brands such as Aquafresh, Panadol, Lucozade and the new weight-loss brand Alli and was responsible for communications strategy across nine European regions and over 100 brands.
Prior to this Hagan spent nearly five years as head of comms at Network Rail, in the leadership team of a department of 130 people, where she had extensive crisis and issues communications experience, including dealing with engineering overruns, UK rail strike threats, and the Cumbria derailment.
She also ran campaigns for some of the UK’s largest and most controversial infrastructure projects including the £5.5 billion Thameslink Programme and the transformation of major stations in the UK.
Hagan started her career at Weber Shandwick working for clients in the financial services, telecoms, transport and FMCG sectors.
Chris Cartwright, managing director, Burson-Marsteller’s corporate practice, said: ‘Sarah has seen things from the client side as well as agency – she has driven strategic initiatives in times of enormous change for complex organisations, dealt with major crises with a level head, and advised C-level executives on key reputational issues in a variety of sectors.
‘She adds significantly to the bench-strength of our growing and award-winning corporate team here at B-M.’
