We are Grant Thornton. We go beyond business as usual, so you can too.

In January 2025, Grant Thornton Advisors LLC and Grant Thornton Ireland officially combined to form a multinational, multidisciplinary platform. This platform affords us with trans‑Atlantic advisory, tax and audit practices. Since then we have welcomed other global firms into our network namely, Grant Thornton UAE, Luxembourg, Cayman Islands, Netherlands, Switzerland & Liechtenstein and Channel Islands.

With these additions, the platform is growing at pace and now encompasses roughly 13,500 professionals across nearly 60 offices, spanning across three continents: the Americas, Europe, and the Middle East.

Our most valuable asset is our people and this transformational step, combines the expertise and reach of both firms, creating tremendous growth and development opportunities for each individual at our network. We operate as one team from multiple locations. This gives each employee the opportunity to work on both national and local projects. Our recent merger with Grant Thornton US affords our staff the opportunity to work on exciting global projects.

We work as trusted advisors and are dedicated to supporting clients across the public and private sector bringing our specialist knowledge and global presence to help businesses succeed. Whether it’s collaborating to build thriving communities, working alongside regulators and financial institutions to build trust, or partnering with a diverse range of businesses, we will address the issues that matter most.

At Grant Thornton Ireland we don’t just predict your future, we build it.
