The new arm will operate as BDO Eaton Square, which BDO said would create 100 management consultant jobs and deliver 30% year-on-year growth for the next three years, achieving €20m ($24.4m) in annual revenues.

Eaton Square is a Irish consulting practice with international experience which was established in 2012 by Aidan McHugh and David O’Connor.

Following the merger of Eaton Square and BDO Consulting, the combined BDO Eaton Square team will have 45 consultants, rising to 145 in three years. The new unit will service clients globally and locally. The jobs will be located across BDO Eaton Square’s locations in Ireland: Dublin, Cork and Limerick.

BDO Ireland managing partner Michael Costello said: “Our motive in merging our existing consulting business with Eaton Square is to create a powerful new force in management consulting, a force that is Partner led and client focused. The combined consulting teams from BDO and Eaton Square, operating as BDO Eaton Square, will do just that that with further expansion plans already underway.

“Eaton Square’s entrepreneurial approach to consulting will work really well with our consultancy team and is a natural fit with BDO’s focus on entrepreneurial businesses in Ireland. The goal for this new consulting team is to become Ireland’s leading team of specialist management consultants and advisers.”
