Palmer-Moore becomes managing partner, with additional responsibilities for talent as the agency looks to increase its workforce. She will also be responsible for overseeing Powerscourt’s service to its clients. Palmer-Moore’s current clients include Aer Lingus, Betfair, ISS and Prudential.
Cohen becomes chief operating officer, taking responsibility for all operational aspects of the business including its planned expansion into new services and markets.
A Powerscourt spokesman said: "This year we are planning to enter new and expand existing service lines. In particular we are looking to develop a more clearly defined public affairs offering as well as strengthening our social and digital capability, an area where we are seeing increasing levels of client activity, to match the high standards of our financial, corporate and crisis practices.
"In terms of recruitment, after a strong end to last year we have taken a lot of momentum into 2015 with a number of new client wins already. Consequently we are looking to recruit for various roles across our four industry sector teams as well as our crisis practice as we look to grow the business further.
"To put that into perspective, five years ago we had 15 staff, 30 clients and a turnover of under £3m. Today we have 35 staff, 70 clients and turnover of £7m."
Rory Godson, founder and CEO of Powerscourt, said: "I would like to congratulate Victoria and David on their very well-deserved promotions. Both have made substantial contributions to grow this firm into one of the City’s leading financial, corporate and crisis agencies in 10 years. This year looks to be our most exciting as we expand into other countries and widen our service offering."
Powerscourt was founded in 2004 by former Sunday Times business editor Godson. It currently advises more than 60 clients.
