Grant Thornton has announced the appointment of 12 new partners to its advisory, tax and audit practices across the island of Ireland, with two of the appointments made at its Belfast office.
Their appointments come at a period of exceptional growth and transformation for the firm, as the Grant Thornton Advisors multinational platform continues to expand following recent strategic transactions with high‑performing professional services firms across the Americas, Europe, the Middle East and the Asia Pacific region.
In the Belfast office, Clare Fitzgerald has been appointed as Tax Partner, with Nikita Lynn becoming an Audit Partner. Meanwhile, new Tax Partners Mark O’Sullivan and Paul McSavage will have all-island roles responsible for Tax Incentives and Transfer Pricing respectively.
The new partner appointments come after the announcement in January that, following the creation of over 70 new roles in its Belfast office last year, Grant Thornton has signed a lease for 23,000 sq ft of office space across two floors in The Ewart on Bedford Square and plans to move into the building in early 2027.
Commenting on the appointments, Steve Tennant, Managing Partner, Grant Thornton Ireland and EMEA CEO of the Grant Thornton Advisors group, said:
“These appointments are a real milestone for the firm and a clear endorsement of the exceptional talent we continue to develop and attract. As we move into our next phase of growth in 2026, our new partners will play a central role in shaping our leadership — bringing deep expertise, strong judgement and a shared commitment to delivering outstanding work for our clients as the pace and complexity of business accelerates.”
The appointment of these new partners reinforces Grant Thornton’s commitment to developing and attracting leading talent, while further strengthening the firm’s leadership team.
Their collective experience enhances the firm’s service offering for clients in Ireland and abroad and reinforces its ability to respond to evolving market needs, delivering solutions for clients now and into the future.
Richard Gillan, Managing Partner, Grant Thornton Northern Ireland, added:
“Congratulations to our colleagues whose appointments to partner reflect the depth of talent across our firm. The appointments come at an exciting time for Grant Thornton as the firm continues to expand across the island of Ireland and internationally. Strengthening our partner group in Belfast is an important part of that journey, ensuring we have the leadership, expertise and ambition required to support our clients as they navigate change, pursue growth and respond to an ever-evolving business environment.”
