Ex-Harper’s Bazaar Australia head of digital joins The Concierge Agency
The former head of digital content and growth at Harper’s Bazaar Australia is among a number of new senior leadership appointments at independent comms, management and content agency, The Concierge Agency, Mumbrella can reveal.
Joining in the newly-created role of managing director, Mariela Summerhays, will be responsible for the agency’s business strategy, alongside founder and director Danielle Williams. She will manage the agency’s resources to sustain its growth.
Summerhays spent just over a year at Harper’s Bazaar, with editorial, commercial and affiliate responsibilities for the publication. She also brings experience from Medium Rare Content Agency, news.com.au, Buzzfeed Australia and Mamamia, among others, to the new role.
“A love of storytelling has guided my career, so to oversee the premium execution of communications, content production and artist management services across The Concierge Agency’s brilliant roster of clients, is truly a wonderful opportunity,” Summerhays said.
“I’ve admired Dani’s intelligence and brilliance for years, and am thrilled that the opportunity to work together has come at this time of growth and transformation for the agency.”
The Concierge Agency has also recently hired Maddison Barber as an account director, and Maisie Dunlop as production and artist coordinator.
Barber has worked across FMCG, sports and media over the past decade, including for the NRL, Carlton & United Breweries, Val Morgan Digital, Are Media and Pedestrian Group. She will manage the team’s publicists, servicing all comms clients including Technogym, KitchenAid, Morrocanoil, Hexclad and Havaianas.

Meanwhile, Dunlop will report to Renee Tappenden, production and artist director, and assist with the coordination of The Concierge Agency’s content productions.
“The appointment of the business’ senior leadership team was part of the vision ensuring we can offer our client roster the most savvy brains in the market,” said Williams.
“As a multi-service agency, we have the best in class strategic brains leading Australian communications and productions for global and local brands.
“Hiring a diverse range of talent means we truly offer a well rounded perspective and skill sets to our clients.
“This allows us to service our portfolio with our unique hybrid communications and production offerings. We’re excited to see what 2024 brings, with a new team, a new HQ and a growing client portfolio.”
Celebrating its fifth anniversary this year, the agency has relocated from its founding Botany office and studio, with plans to move into a fully refurbished, experiential office and showroom in Darlinghurst, in mid-July.
