Back

Grant Thornton is a leading multinational professional services firm in Ireland, with approximately 2,800 people in offices across the island of Ireland, Bermuda, Isle of Man and Gibraltar. Its tax, audit and advisory teams work with organisations across sectors including technology, insurance, asset management, banking, life sciences, and aviation, as well as the public sector. It aims to deliver practical solutions to help organisations achieve their goals, while maintaining a position as a leader in sustainability through long-term value creation, ethical practices and positive social impact.

In 2025, Grant Thornton Ireland formed a multinational, multidisciplinary platform with Grant Thornton US. The platform offers a premier advisory and tax practice, as well as independent audit practices. The platform continues to expand, with 60 offices from the Americas across Europe to the Middle East, delivering a singular client experience that includes enhanced solutions and capabilities, backed by powerful technologies and a roster of over 15,000 quality-driven professionals enjoying exceptional career-growth opportunities and a distinctive cross-border culture.

As a member of Grant Thornton International—a global network of more than 73,000 passionate people across more than 150 countries - it strives 'to bring local knowledge, national expertise and global presence to help businesses succeed, wherever they’re located.'

Managing Partner Stephen Tennant commenting on the firm's merger with its US affiliate said, 'Our agreement in late 2024 to combine with Grant Thornton Advisors in the US has been a catalyst for creating our multinational platform, now spanning the Americas, Europe, and the Middle East. This platform continues to expand, providing clients with access to an extensive array of industry expertise and innovative solutions, bolstered by substantial investments in technology and talent.'
