Publicis London adds senior creative hires

Publicis London has appointed Bronwyn Sweeney and Loren Cook as Global Creative Directors, expanding its senior creative leadership team under Chief Creative Officer Noël Bunting.

The appointments introduce two newly created roles and see the pair working alongside Noël Bunting to shape the agency’s global creative output across its international client portfolio.

Creative leadership expansion at Publicis London

The hires follow a strong period for Publicis London in 2025, during which the agency added clients including Electrolux, Foster’s and Marriott Bonvoy. The agency also recently launched La Porte, an initiative designed to support internationally focused junior creative talent.

Bronwyn Sweeney and Loren Cook have worked as creative partners since 2016. They join Publicis London after nearly a decade at MullenLowe, where they led work for brands including Ferrero, Bupa and Unilever.

Award-winning global creative work

Among their most recognised campaigns is Persil’s Wash Away the Taboo, which addressed stigma around menstruation through intimate storytelling. The work received multiple international accolades, including a Cannes Lion. In 2024, the duo were named Team of the Year at Campaign’s Agency of the Year Awards.

Alongside the Global Creative Director appointments, Publicis London has also hired Liam Crerar as Senior Creative. Originally from New Zealand, Liam Crerar has previously worked at Neverland and Droga5 in London, as well as Clemenger BBDO and Ogilvy in Auckland.

Bronwyn Sweeney, Global Creative Director, Publicis London: "Publicis London feels ambitious, down-to-earth and creatively driven, so is a great cultural fit for us. The agency’s campaigns demonstrate everything global work should be – exciting and emotionally engaging. We can’t wait to get stuck in."

Global ambitions and creative culture

Loren Cook, Global Creative Director, Publicis London: "We have always thrived in environments where creativity and kindness go hand in hand. Publicis London is full of fun, talented people who care about the work and about each other, which makes it a brilliant place for us to be, to create ideas that will resonate worldwide."

Noël Bunting, Chief Creative Officer, Publicis London: "Bronwyn, Loren and Liam are outstanding creatives. Their work is thoughtful, ambitious and has shown lasting impact. Their global experience and outlook make them all a natural fit for Publicis London, and I’m delighted to watch how their ideas will take shape and move the world."
