The legal team at Hilton Worldwide Holdings Inc. makes sure the doors can stay open at the company's more than 4,300 properties and that management, shareholders and regulators have a smooth experience with the legal department.

Hilton's 58-attorney legal department recently shrunk its outside-counsel list, revamped how its reviews those firms and enhanced Hilton's compliance ­programs.

General counsel Kristin Campbell's team juggled those projects with the groundbreaking $1.95 billion sale of the Waldorf Astoria New York this year and ongoing pro bono commitments. Diversity is also important for the legal team, where women make up 43 percent of the attorneys and 70 percent of the overall staff in the department.
