Starting next month, Elliott will be tasked with growing a corporate comms offer across the agency’s European and South East Asian network.
The move follows nearly nine years at FTI Consulting – formerly Financial Dynamics – and two decades working in the PR and public affairs industry.
Referencing links with "strategic hubs" in Dublin, London, Brussels, Paris and Singapore, Hume Brophy’s CEO Conall McDevitt said:
"Simon’s appointment will significantly strengthen our offer across our existing territories and will allow us to expand into new ones."
Elliott plans to recruit sector specialists into the new practice with a particular focus on the agency specialisms of aerospace and defence, financial services, energy and property communications.
He said: "Hume Brophy has one of the strongest track records in the markets where it has a presence and is clearly a business destined for even greater success.
"The opportunity to participate in a global leadership role in the next stage of its growth is clearly a unique opportunity to which I am very much looking forward."
FTI has brought in Alex Deane from Weber Shandwick to build up its public affairs offering as MD.
