Although her decision to join a small operation may surprise some (Barrett Cernis ranks 217th in the MMS billings league), Grimes is very positive: "The agency is very good at what it does and has lots of fun. It's open minded about how I want to work. How could I refuse? she said.
The £10 million billing shop's biggest client is Britvic, with which it has a steadily growing relationship. It recently launched a £1.5 million campaign for Britvic's J2O to support the soft drink range's move to a wider market.
Justin Cernis, the agency's managing director, said: "I know that with Janet joining we probably have the most respected planner in the industry as part of our team. It demonstrates our ambition to be a quality shop."
Grimes' arrival in September will culminate a three-month search by the agency to find a planning chief.
She will not initially have equity in the agency, which is currently divided between Cernis and Ray Barrett. But Cernis said: "We will move toward a profit-sharing and equity scheme at some point and Janet will participate in that."
