In addition to jointly running the corporate group, Mr Fitzgibbon has also taken on the role of head of corporate M&A and Mr Maher has joined the firm’s management committee.

Ms Stone has also rejoined the management committee following her recent return from maternity leave.

The appointments, which take immediate effect, follow the completion of Robert O’Shea’s term as head of corporate and Brian Doran’s tenure as head of commercial real estate.

Michael Jackson, Matheson’s managing partner, said: “These appointments are a significant marker for Matheson and are just one example of the growth which the firm has created in two important practice areas.

“Our corporate team has consistently led the market in recent years, working on some of the most complex and challenging M&A deals in Ireland, and under the leadership of Darren and David I am confident that this will continue.

“Likewise, our growing commercial real estate team has been central in advising on some of the most high-profile developments in the country and with Sally Anne’s proven skills and experience, this critical area will undoubtedly grow.”

He added: “I congratulate Darren, David and Sally Anne on their appointments and thank their predecessors Robert and Brian on the completion of highly successful terms.

“They have collectively made significant contributions to the continued success of two of our core practice areas as we continue to serve our clients here and across our international markets, and I look forward to continuing to work with each of them in their new roles.”
