The international growth story

The international growth story of Grant Thornton dates back to the early 1900s in Scotland. The company was founded in 1904 under the name Thornton, Baker & Co. Scottish accountants Alexander Grant and William Thornton joined forces to establish an auditing firm.

Over the following decades, the company grew and expanded its presence. In 1959, Grant Thornton opened its first international office in the United States, marking a significant step towards internationalization. In 1975, Thornton, Baker & Co. and the American firm Alexander Grant & Co. merged to create the globally recognized network known as Grant Thornton. Over the years, numerous firms from around the world have joined this network.

Today, Grant Thornton is one of the world's largest accounting firms, operating in over 140 countries with thousands of professionals in its employ. The Grant Thornton network consists of several independent member firms operating in different countries. The collaboration and shared values among these member firms enable a vast global network, offering local expertise and international capabilities to serve their clients.
