            We are Grant Thornton United States

            Grant Thornton LLP is the US member firm of Grant Thornton International Ltd, one of the world’s leading organisations of independent audit, tax and advisory firms. The firm was founded in 1924 as Alexander Grant & Co. In 1980, we joined with other international accounting firms to form Grant Thornton International Ltd. Our people and our services are built around our clients’ locations, service needs and industries. Collaboration and coordination across the geographic, service-line/industry matrix enables us to provide the personalised attention and a high level of client service for which Grant Thornton is known. 








            Global strength

            Grant Thornton is one of the world’s leading organisations of independent assurance, tax and advisory firms. With 47,000 Grant Thornton people, across more than 130 countries, we are focused on making a difference to clients, colleagues and the communities in which we live and work.

            Why Grant Thornton

            Our clients get more one-on-one time with our partners and faster responses to the critical issues that impact their operation. With more on-the-ground time on site, our partners gain valuable knowledge about our clients’ environment.

            We’re a big organisation. Our clients can expect the resources, skills and experience of a much larger firm, but with the accessibility and attention of a much smaller firm.


            Grant Thornton is an award-winning globally recognised professional services network. Here are some of our awards:

            MCA Project of the year 2015
            Best Programme for Leadership Development in 2015
            IAB Employer of the year 2014
            Global network of the year 2013
