During three decades of convulsive change, marked by nationalization, globalization, megamergers and spectacular flameouts, it’s surprising how much has remained constant at the top of the NLJ 250.

Baker & McKenzie still sits at the top of the NLJ’s annual survey of the nation’s 250 largest law firms. Firms that originated in New York and Chicago accounted for about half of the top 25 back then and still do so today, though some of the names have changed and the tilt is now more toward Chicago than New York.
