Steeped in 'real word experience', Cleary Gottlieb Steen & Hamilton excels in providing strategic, high-level counsel to systemically important financial institutions (SIFIs). Utilizing the expertise of lawyers across numerous international offices, a key part of the firm's success in the area is its ability to provide coordinated advice that is mindful of regulatory concerns not just from a US perspective but from a global one.
