Voyle (pictured) joins the agency from Tulchan and brings more than 25 years' experience across capital markets, corporate advisory, reputation management, crisis and issues management and journalism.
She was a partner at Tulchan for 15 years, and prior to working in comms spent more than a decade as a journalist at the Financial Times.
"I’m joining a first-class team from diverse backgrounds, all focused on delivering a rounded offer to a rapidly growing client base," Voyle said.
"There’s a real sense of purpose and momentum here and I look forward to playing my part in driving this business forward."
Additionally, Pellew has been promoted with immediate effect to partner. Pellew joined Headland in 2014 and has more than 12 years of public affairs and crisis management consultancy experience.
CEO of Headland Chris Salt welcomed both moves, and said of Voyle: "It’s a pleasure to welcome Susanna, who is one of the most experienced advisors in London.
"She’s been right at the sharp end of corporate and financial communications for many years. Her track record, along with the quality of her advice in the boardroom, adds a great deal to our rounded offer."
Headland has had a stellar 2018, growing annual revenue by 56 per cent to £11m, according to the PRWeek Top 150 Consultancies report.
This made Headland the second-fastest-growing consultancy among the Top 150 in 2018.
