Chrysostomou was previously head of external comms at Kent County Council and has held roles in the Foreign Office and Central Office of Information.
Chrysostomou said: "With a more buoyant economy, I can use my experience and skills to help businesses realise their ambitions through growing their profiles and helping them reach new markets by understanding both the needs of the business and the customer."
Zoodikers MD Katie King said: "We’re seeing real demand from our clients for senior consultants who understand the impact that the changing world of communications is having on their business and its multiple stakeholders. As Forbes predicted, marketing media are merging, with content marketing, SEO, PR and social media all blending into one skill set. It’s a time of real opportunity for agencies with the correct skill sets and senior experience."
