The World, Olympic and Commonwealth 400m champion has tasked the agency with handling her comms strategy, media relations and national and international profile.
Ohuruogu received a one-year ban from all competitions in August 2006 after she missed three out of competition drugs tests and has endured a sometimes uneasy relationship with the press and public since.
Despite winning Great Britain's only track gold medal in Beijing, she failed to make the top three for the BBC's Sports Personality of The Year Award and has yet to receive the same public affection as other recent Olympic gold winners on the track, such as Dame Kelly Holmes, Denise Lewis and Sally Gunnell.
The agency will also work in collaboration with Ricky Simms of PACE Sports Management on commercial sponsorship opportunities for the athlete.
Ohuruogu commented: ‘With the upcoming IAAF World Championships in Berlin this is a very important year for me and I am looking forward to defending my title. The Vero team have a real understanding of what motivates me as an athlete and insights and ideas about how to bring this to life from a media perspective.
'While my focus at the moment is training and preparing for the Championships, I am very excited by the prospect of injecting new energy into my communications and commercial activities and connecting with my fans in innovative and exciting ways.'
