Deloitte’s people are problem-solvers, creating change and making a difference in everything they do. And that’s not surprising: Innovation and problem-solving are in our organization’s DNA. Our founder William Welch Deloitte was the first person ever appointed as an independent auditor of a public company. That was in London in 1845. His company went international when he added a New York City office in 1880. Today, William Deloitte’s vision lives on through the nearly 200,000 partners, principals, and employees of the worldwide Deloitte Touche Tohmatsu Limited (“DTTL”) organization of member firms, providing services in audit, advisory, tax, and consulting. Today, Deloitte employs more than 70,000 U.S.-based professionals in over 100 offices across the country.
