The pharmaceutical-specialist agency won the accolade at the Yorkshire Post Excellence in Business Awards 2009.
World Events managing director Martin Parry said: "We are delighted to have won, particularly as we have achieved Investors in People accreditation and the ‘first class' star status for employee engagement in the Sunday Times Best Companies to Work For 2009 survey. As the company has grown, we have tried to retain our culture and values and view our staff as an integral part of our success."
World Events doubled its staff and grew its turnover and profit by 30% between 2007 and 2008. It was also named Agency of the Year at the Eventia International Awards 2009.
