The hugely experienced sports marketing expert joins from the Coca-Cola Company where he was involved with the strategic planning and operational delivery of Olympic Games and FIFA World Cup sponsorships since 1998 and is currently deputy general manager for its sponsorship of London 2012.
"I am looking forward to joining SportAccord at such an important moment in the development of the organisation," said Gaillard.
"SportAccord is a dynamic structure with enormous potential, leading several ambitious initiatives for the benefit of the international sports movement.
"One of my main tasks will be to consolidate recent developments and, at the same time, further develop multi-sports games and various other initiatives.
"But our focus will always remain to unite and support SportAccord members."
Gaillard was most recently in charge of the Coca-Cola Company's activation of the Beijing 2008 and London 2012 Olympic Games, with a specific responsibility of implementing large-scale sustainability initiatives with several non-governmental organisations.
Prior to joining Coca-Cola he held different sports marketing roles with the National Basketball Association in Switzerland, BBDO Advertising in France and with Adidas in Germany.
