Since it was first published in 1983, Best Lawyers® has become universally regarded as the definitive guide to legal excellence. Best Lawyers lists are compiled based on an exhaustive peer-review evaluation. Lawyers are not required or allowed to pay a fee to be listed.

Only a single lawyer in each practice area and designated metropolitan area is honored as the “Lawyer of the Year.” Lawyers honored as “Lawyer of the Year” are selected based on particularly high voting averages received during the peer-review assessments that Best Lawyers conducts with thousands of lawyers each year. Receiving this designation reflects the high level of respect a lawyer has earned among other lawyers in the same communities and the same practice areas for their abilities, their professionalism, and their integrity. The “Lawyer of the Year” Award is allocated annually to the lawyer who has the highest overall peer-review feedback in a certain practice area for a particular geographic region.
