With about 2 million people and a fairly steady economy that leans heavily on agriculture and manufacturing, the Kansas City, Mo., metropolitan area hardly rivals New York, Chicago or Los Angeles when it comes to demand for legal services. Yet the city is home to quite a few sizable law firms — four of the 250 largest U.S. law firms are based there, with an additional three firms headquartered elsewhere but maintaining a significant presence.

A spate of mergers during the past decade has produced a local legal landscape dominated by firms with 300 or more attorneys and smaller boutiques.
