According to an industry source, Stephanie Bell is taking on a regional media head role (excluding China, Australia, Japan and Korea ) at L'Oreal.
Bell stepped down as CEO of GroupM Thailand on 23 July, after being with Mindshare since 2002.
Initially appointed as the MD of the Philippines office, she moved to Thailand in 2004 to work on the Unilever business and develop other brand content. She was promoted to managing director in January 2006 and became CEO in July 2008, based out of the group's Bangkok office.
L'Oreal has been involved in a flurry of pitching activity, both traditional and digital, across the region over the past year.
The cosmetics giant launched a review of its US$45 million media account in Australia this month.
In India, Maxus clinched agency-of-record for L'Oreal in July while Mindshare Hong Kong managed to keep hold of the account following a statutory review in December. L'Oreal also reappointed UM to handle its media in Japan last year.
