The event agencies' new partnership is aimed at significantly improving both companies' ability to save on costs and improve their client services.
The agencies will collaborate on client briefs to share knowledge of the European and US markets.
"We're receiving an increasing number of briefs for meetings in the US and it makes sense for us to have a trusted and reliable partner in North America whose resources, knowledge and experience we can tap into," said Oxford International managing director John Walker. "Our two organisations complement each other perfectly. Not only are our client bases predominantly pharmaceutical, but we're both independent agencies and we share the same values and operational approach."
