LOS ANGELES — London’s Bubble Agency has officially expanded to the US, opening a Los Angeles office that will operate under the name Bubble Agency Inc.

The Los Angeles office will serve as headquarters for the new operation, which will be led by Americas head Kim Willsher.

Willsher joins after leading Red Lorry Yellow Lorry's LA office for 11 years, during which she also oversaw global campaigns for media and entertainment clients. She worked for Red Lorry Yellow Lorry in London for six years before that.

“I am so pleased to welcome Kim to the team. She has a reputation for being one of the finest PR professionals in the industry, and her connections and contacts will enable Bubble to build on our existing presences in the Americas and continue to transform businesses with our knowledge and network,” said managing director Sadie Groom.

Opening the new office formalizes Bubble Agency’s presence in the US, where it has tapped publicists and content writers to handle projects for more than a decade. The firm’s regional growth over the last six months, which includes the addition of tech clients such as Xencelabs and GridMarkets, precipitated the move at this time.
