Since its inception in 1983, Best Lawyers has become universally regarded as the definitive guide to legal excellence. Because Best Lawyers is based on an exhaustive peer-review survey in which more than 32,000 leading attorneys cast almost two million votes on the legal abilities of other lawyers in their specialties, and because lawyers are not required or allowed to pay a fee to be listed, inclusion in Best Lawyers is considered a singular honor. Corporate Counsel magazine has called Best Lawyers “the most respected referral list of attorneys in practice.”
