About Grant Thornton LLP

Grant Thornton LLP (Grant Thornton) is the U.S. member firm of Grant Thornton International Ltd, one of the world's largest organizations of independent audit, tax, and advisory firms. Grant Thornton, which has revenues in excess of $1.6 billion and operates 59 offices, works with a broad range of publicly and privately held companies, government agencies, financial institutions, and civic and religious organizations. The company's "bring your whole self to work" philosophy stresses diversity and a culture of flexibility and empowerment among its staff. 

Alexander Richardson Grant, the namesake of the firm, began his accounting career at Ernst & Ernst (a predecessor of Ernst & Young), but, at 26, decided it was time to be his own boss and opened Alexander Grant & Co. in 1924. The company eventually became Grant Thornton in its current form, and seeded the creation of Grant Thornton International in 1980 when 50 international accounting firms formed a global organization.
