DUBLIN, IRELAND — Grant Thornton has appointed 12 new partners across its advisory, tax, and audit practices in Ireland, a move that significantly bolsters its leadership team during a period of exceptional growth.
The appointments come as the firm’s multinational platform, Grant Thornton Advisors, continues to expand following recent strategic transactions with high-performing professional services firms across the Americas, Europe, the Middle East, and Asia Pacific.
Strategic growth fuels leadership expansion
According to Managing Partner Steve Tennant, the appointments will mark a milestone that will put the firm on the next stage of its growth in 2026 by 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 management reinforcement is a direct response to changing market requirements, enabling the company to deliver strong solutions to its clients, both in Ireland and abroad.
This action also extends the overall investment plan of the Grant Thornton Advisors multinational platform, which is aggressively consolidating high-performing companies across all major world markets.
The company is also expanding its capabilities to support multinationals by strengthening its leadership centre with seasoned professionals with experience not just in the country but globally.
The total experience of the new partners is geared toward enhancing the firm’s service offerings, making it more agile and capable of meeting complex, cross-border client demands.
Deepening expertise across audit, tax, and advisory
The newly appointed partners bring a wealth of specialized knowledge to Grant Thornton’s core service lines, reflecting the firm’s commitment to developing and attracting leading talent.
In the audit practice, appointees like Sinéad Barrett, a firm veteran since 2004 now specializing in global statutory audits for shared service centers, and John Botha, a leader in the construction and engineering sector with 24 years of experience, highlight the depth of internal talent.
The addition of David Carroll, a partner focused on capital markets and asset management, signals a strategic push to deepen the firm’s foothold in complex, regulated financial sectors.
The tax and advisory practices have also been enhanced considerably, with professionals of diverse qualifications.
The tax team is highly experienced, with partners such as Julia Considine, with over 17 years of experience in the succession planning practice, Clare Fitzgerald, who has a multidisciplinary background in engineering and computer science with over 18 years of experience, and Mark O’Sullivan, who has over 17 years of experience in the successful tax reduction practice.
At the advisory level, the hiring of David Mac Curtain as the head of the actuarial and insurance risk practice and of Shane Quinn as the head of the global financial crime compliance teams shows that the firm is working towards creating focused centers of excellence to serve its clients globally.
Focus on high-demand specialisms and international capability
One of the major themes of the appointments is a targeted approach to high-growth and high-complexity areas, providing Grant Thornton with an opportunity to meet sophisticated client demands across the global jurisdiction.
The company has also strengthened its performance in specialized fields, such as transfer pricing through the recruitment of Paul McSavage, who has more than 20 years of international experience, and wealth advisory with Liam Naughton, who specializes in high-net-worth individuals.
This focus is mirrored in the audit practice, where partners like Zeno Kelly and Nikita Lynn bring extensive experience managing complex audits for multinational corporations and SEC registrants under both IFRS and US GAAP.
The collective international experience of the new partners positions Grant Thornton to better serve clients operating across Europe, Africa, the Middle East, and the Americas.
Many of the new partners, such as John Botha and Nikita Lynn, have direct experience managing multi-jurisdictional engagements or holding senior roles in global companies.
This international outlook, combined with specialized skills in aircraft leasing, private equity, and financial crime compliance, enables the firm to offer integrated solutions.
The appointments are a clear endorsement of the firm’s strategy to attract and develop leaders who can deliver outstanding work as the pace of business accelerates for its global clientele.
