Mr Byrne is currently head of the banking and finance department at Addleshaw Goddard Ireland. He will lead the firm’s Ireland business, which comprises 160 people in its Dublin office. The firm supports clients across a broad range of sectors and practice areas in Ireland and internationally through the Addleshaw Goddard network of offices, which advises clients in over 100 countries.

Commenting on his appointment, Mr Byrne said: “I am incredibly honoured to be appointed head of Ireland at Addleshaw Goddard. We have built a strong and successful business in Ireland, and I am committed to working alongside our talented partner group across the firm to build on our achievements, deliver on our AG2030 strategy and drive forward the next phase of growth for our Irish practice as part of an increasingly international business.

“The firm has experienced significant growth in recent years, and I would like to thank Mark Walsh for his outstanding leadership and contribution during that time. From this strong foundation, we will continue to invest in our people, strengthen our client relationships and further enhance our position in the Irish market.”

Mr Walsh said: “I am delighted to congratulate Ray on his appointment. He is an exceptional lawyer and leader who is highly respected by colleagues, clients and peers alike. Addleshaw Goddard’s business in Ireland will continue to thrive and grow under Ray’s leadership.

“It has been a privilege to serve as head of Ireland over the past five years and to have steered the successful merger between Eugene F. Collins and Addleshaw Goddard in 2022. I am grateful for the support of my colleagues and clients throughout that time and look forward to supporting Ray as he transitions into the role.”

Andrew Johnston, global managing partner of Addleshaw Goddard, said: “Mark has made an exceptional contribution to our firm. His vision and leadership have helped transform Addleshaw Goddard in Ireland into the successful international law firm that we are today.

“I look forward to working closely with Ray as we continue to grow our business and support clients both domestically and internationally. Ireland is a strategically important market for Addleshaw Goddard, and I am confident that we will maintain our positive momentum under Ray’s leadership of our Dublin office.”

From the first of January 2027 Piaras Power will step into Mr Byrne’s role as head of banking and finance.
