Traditionally known more for public affairs, the agency is keen to step up its corporate presence and has recruited Grindon as director designate to help spearhead this drive.
She joins after more than five years with Freuds, representing clients including Asda, PepsiCo, Nike, Samsung and Eurostar. She also had spells at Weber Shandwick and Propeller Communications.
Graham McMillan, chief executive of Open Road, said: 'We have a great platform in corporate comms on which to build, while continuing to grow our public affairs and corporate responsibility business.
'Rebecca will help to drive this with her experience of corporate reputation and corporate brand work with major companies.'
