Attivo Group-owned full service agency, 303 MullenLowe Sydney, has announced a new senior leadership structure, spearheaded by the promotion of Joanna Gray to the newly created role of Sydney CEO, and the appointment of Karen Coleman as Sydney Managing Director.

Karen joins the agency after four years as Managing Director at Archetype Australia, where she forged a transition from a pureplay PR consultancy to a fully integrated marketing agency.

In their respective new roles, Joanna will continue to drive new business growth and develop the agency’s newly formed specialisations, such as 303 Health, while Karen will lead the agency’s operations with a key focus on building high performance teams, further growing integrated solutions for clients and driving the productisation of services.

The duo will also work side-by-side with 303 MullenLowe's Perth MD, René Migliore, while also continuing to collaborate across Attivo’s other agencies in ANZ and the U.S.

Joanna said: "We’re excited about this partnership. Karen has the proven business leadership to really drive new opportunities in this role - particularly through her significant tech category experience and supercharged, of course, by her trademark energy and smarts."

On joining the agency, Karen said: "Through a particularly harmonious end-to-end capability, 303 MullenLowe has developed a culture of delivering disproportionate outcomes to its clients over the years - something we like to call 'creating unfair advantage'. It's the perfect response to the high-level consulting that clients are demanding these days. Especially as we continue to navigate significant economic challenges. I’m looking forward to partnering with Jo and the entire 303 MullenLowe leadership team to both continue and evolve this story."
