René Migliore, 303’s Perth managing director, is stepping down after a 14-year career with the agency spent over two separate stints.
The office will be overseen by Perth chief strategy officer Matt Oakley and general manager Kylie Macey, supported by Attivo CEO Sue Squillace and executive chairman Anthony Gregorio as well as the local senior leadership team.
Migliore has led the agency’s Perth office since 2019 when it was named 303 MullenLowe. He first worked at the business in 2006 and left in 2013, before returning a general manager in 2017.
During his tenure, Migliore was one of the architects of a shift within the Perth office, embracing 303’s entrepreneurial roots, expanding its capabilities beyond traditional advertising and hiring world-class talent.
This transition saw the agency taking on a diverse array of strategic business, media and brand projects that pushed creative boundaries and strengthened its position in the market.
The agency rebranded from 303 MullenLowe to ‘303’ in the wake of Omnicom’s takeover of Interpublic Group.
“I’ve always been a strong believer in the 303 brand, our work and our incredible people. Together, we’ve worked hard to build a rich ensemble and more diverse capabilities that enables the agency to tackle a wider array of client challenges, from business strategy to brand planning to creative, media, and design solutions,” he said.
“This evolution has been rewarding, and an effective strategy for us in this market. I’m supremely confident and excited to see this team driving 303’s success.”
Squillace said: “As leader of the Perth business, René has dedicated himself to delivering bold creative, media, and business solutions tailored to the local market. This commitment has seen him attract a talented leadership team that will continue his legacy of collaboration and new media thinking.
“We thank him for the years he has given to this company, his mentorship within the agency and the broader industry, and his tireless advocacy of Western Australian creativity. We look forward to seeing where he will apply his passion and talent next.”
303 is part of the Attivo Group, with agencies including Mediahub, Tonic Communications, Farrimond, DNY and Hill Holliday.
