Deloitte LLP

In the United States, Deloitte LLP and its subsidiaries have 57,000 professionals with a single focus: serving our clients and helping them solve their toughest problems. We work in four key business areas — audit, financial advisory, tax and consulting — but our real strength comes from combining the talents of those groups to address clients’ needs. Fortune and BusinessWeek consistently rank our organization among the best places to work, which is good news for our talent and our clients alike. When the best people tackle the most compelling challenges, everyone wins.
