Joining as European healthcare MD, Pay reports jointly to WS UK and Ireland CEO Colin Byrne and global healthcare president Laura Schoen in the US.
She is based in the UK but will work across WS's 50 offices across Europe.
Working on pan-European accounts including Pfizer, Eli Lilly and Roche, Pay replaces Fiona Hall who joined Chandler Chicco Agency last July.
She previously worked in sectors including dermatology, women's health, urology, oncology, animal health and endocrinology.
‘The healthcare practice is growing at an incredible rate across Europe,' said Schoen.
Lucie Harper remains MD of healthcare in the UK and continues to report to Byrne and Schoen.
Last month, Edelman Europe president and CEO David Brain predicted that a healthcare sector boom would fuel major agencies' growth in 2007, in a PRWeek ViewPoint video (PRWeek, 11 January). Pay, Byrne, Harper and Schoen were unavailable for comment.
