The expansion reinforces the Belfast-based law firm’s position as a leading adviser on complex, high value corporate transactions across Northern Ireland and beyond.
Responding to sustained client demand, Mills Selig continues to scale its corporate offering, providing sophisticated, commercially focused advice on mergers and acquisitions, private equity, corporate governance, joint ventures, shareholder arrangements, and wider transactional work.
Led by Managing Partner Chris Guy, the expanded Corporate team includes Senior Partner John Kearns, Partners Glenn Watterson and Darren Marley, and newly appointed Commercial Partner Aisling O’Hare.
