Bullfrog unveiled new appointments to its executive leadership team, with Georgia Newton as General Manager, Mike Ronkoske as Chief Strategy Officer, and Tim Shelley as Chief Brand & Experience Officer.
Newton joins the agency from Daniel’s Donuts, where she was Head of Marketing, and brings experience from agencies including Special Group Australia, Goodby Silverstein & Partners, and R/GA New York. Her client work spans brands such as Samsung, Verizon, BONDS, and Chobani.
Newton said of her new role: “Bullfrog is a rare mix of ambition and commercial clarity. The team is world-class, and the momentum is undeniable. We’re driven by talent, powered by insight, and grounded in the grit to deliver work that drives real growth. There’s serious potential in the building, and I’m excited to help unlock it.”
Ronkoske takes on the Chief Strategy Officer role with two decades of strategic leadership across the U.S. and Australia, including roles at Neighbourhood Strategy, Clemenger BBDO, Goodby Silverstein & Partners, and Saatchi & Saatchi LA. His portfolio includes Nike, Atlassian, Ford, Audi, and Cisco.
“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. Add in a warehouse of fun, generous people and a business model that backs what we believe in — it was a no-brainer decision for me.”
Shelley, now Chief Brand & Experience Officer, has spent the past three years at Bullfrog and previously held senior creative roles at AKQA, Ueno, SouthSouthWest, Leo Burnett, and Isobar. He has worked with clients including Google, Linktree, Levi’s, and IBM.
“The energy in the pond right now is electric,” Shelley said. “We’ve built something special at Bullfrog over the past few years, and having the opportunity to shape what’s next alongside Georgia, Mike and the broader team is something I’m immensely proud to be part of.”
Additional executive leadership team appointments will be announced in the coming months. The appointments follow the recent promotion of Phoebe Sloane, formerly Senior Copywriter at Clemenger BBDO, to Creative Director.
