In 1972 Jim Polsinelli and colleagues formed the firm to serve business and real estate clients in a small office in the historic Country Club Plaza District in Kansas City, Missouri. The firm has continued to see impressive growth over its 40+ year history with expanding practice areas and office additions, most recently in Seattle. The addition of these offices is part of our strategic plan to better serve the increasing needs of our clients.

Doing so has allowed us to attract experienced attorneys across the country seeking a platform best suited to their clients’ priorities. With our firm’s concentration of presence in lower-overhead markets, we are able to offer more comprehensive services than local or regional firms and more competitive overall cost than national firms concentrated in higher cost markets.
