When law firm leaders think about growing in New York City, they often think about the city’s big-ticket industries: real estate, mergers and acquisitions, banking and insurance, to name a few. At Perkins Coie, office managing partner Keith Miller is thinking about blockchain.

Seattle-based Perkins Coie, whose $862 million in revenue makes it the 45th-highest grossing firm in the Am Law 100, set up shop in New York City with one lawyer in 2011 after having built up a presence across the U.S. and in China. On the East Coast, it’s still best known for its Washington, D.C.-based political law practice, which counts the Democratic National Committee among its key clients.
