Georgia Newton, Tim Shelley, Mike Ronkoske.
Independent creative agency Bullfrog has appointed Georgia Newton general manager, Mike Ronkoske chief strategy officer and Tim Shelley chief brand and experience officer to its new executive leadership team.
The appointments follow the recent appointment of Phoebe Sloane, former senior copywriter at Clemenger BBDO, to creative director.
Bullfrog was founded by Dalton Henshaw.
"Bullfrog is a rare mix of ambition and commercial clarity," said Newton, who brings a track record spanning top creative agencies and client-side leadership.
Newton was most recently head of marketing at Daniel's Donuts and previously held senior roles at Special Group Australia, Goodby Silverstein & Partners and R/GA New York. Her portfolio includes campaigns for XFINITY, Samsung Global, Verizon, BONDS, Coopers Brewery and Chobani.
Ronkoske brings two decades of cultural and behavioural change experience across global agencies and strategic consultancies. He has led work for Sonos, Nike, Porsche, Ford, Atlassian, Audi and Cisco, with previous roles including head of strategy at Neighbourhood Strategy and strategy partner at Clemenger BBDO.
"I don't believe in fate, but joining Bullfrog just makes sense," Ronkoske said. "Dalton has built a strong foundation and given me a clear mandate to deliver a fresh strategic approach for the next phase of growth."
Shelley steps into his role following more than 16 years as an internationally recognised creative leader, having worked with Google, Levi's, Strava, Honda, Audi and SPC. Over the past three years at Bullfrog, he has helped shape the direction of the agency and led transformative outcomes as an embedded head of brand for both Linktree and Kic.
Before joining Bullfrog, Shelley was creative director at AKQA in the US.
Additional executive leadership team appointments will be announced in the coming months.
