During the past 16 months, Dorsey & Whitney partner Cassandra Headrick has rubbed elbows with some of the most powerful players in the legal profession: Wal-Mart Stores Inc. general counsel Karen Roberts; U.S. Securities and Exchange Commission Chairwoman Mary Jo White; Microsoft Corp. general counsel Brad Smith.

Headrick, who became a partner in 2010, wasn’t just making small talk at a cocktail hour with these legal leaders. She was touring their legal departments, learning how they operate and picking up leadership advice.
