Armour was tapped to set the creative vision, oversee creative development, recruit top talent and guide new business creative efforts, working closely with worldwide chief creative officer John Patroulis.
Armour spent the last three years at 72andSunny, becoming executive creative director and overseeing clients such as General Mills, Diageo, Spotify, Trojan, Halo Top and Marcus by Goldman Sachs.
Michael Houston, worldwide chief executive officer of Grey Group, said: "We are delighted to welcome Justine to Grey New York. She is bringing her unique creative talents to help our clients build some of the world's strongest brands. Her work sells, entertains and becomes part of the cultural conversation in tune with our 'Famously Effective' philosophy. Her arrival underscores our ongoing investment in assembling the best bench of creative leaders in the world."
Armour began her career in Australia at McCann Erickson Brisbane before moving to the US, where she spent five years at Wieden+Kennedy.
“Justine brings a deeply impressive creative pedigree, a reputation for work that’s famous in the world as well as in the industry, and a thoroughly modern approach to leadership," Patroulis said. "Not every great creative becomes a great creative leader. Justine has proven again and again, on big brands and at great agencies, that she’s both. She’s a special talent - a smart, funny and generous human - and we’re thrilled she’s joining Grey New York at a such an exciting time.”
Armour added: "I’ve been watching with interest at Grey’s reinvention over the past couple of years. When they committed 75% of their talent investment to creative, I thought that was radical and I was curious to see how it would play out. Since then, I’ve seen good people going in, and I’ve seen really nice work coming out. I will be a force for continuing that momentum as we start a brand new decade together."
72andSunny said this of Armour: “Justine’s fearless creative leaps and brave leadership style helped set up 72andSunny New York with a ton of momentum going into 2020. We wish her nothing but the best in her new role and are excited to see how she’ll continue to push the industry forward.”
Other recent hires by Grey include Javier Campopiano as chief creative officer, Grey Europe and Global Clients and Cory Berger as worldwide chief marketing officer.
