GallieGodfrey will focus on campaigning work using a combination of marketing, brand building, press and public affairs.
The agency launches with a campaign championing the role of fathers. It has been appointed by UK think-tank The Fatherhood Institute and will launch a major drive early next year, building towards Father's Day next June.
GallieGodfrey is considering running a 'Britain's best dad' awards night. It is currently in talks to find a national broadcast or print media partner.
In addition, GallieGodfrey will lobby regulators to improve policies for fathers in the workplace and the economy.
Godfrey said: 'We have seen the impact of crime and antisocial behaviour on kids who do not have male role models. It is an area where the Government wants to make improvements.'
