Super Lawyers is a national rating service that rates attorneys in all 50 states. The selection process utilized by Super Lawyers is multi-phased and includes independent research, peer nominations, and peer evaluations. One court recently had this to say about Super Lawyers:

“[T]he selection procedures employed by [Super Lawyers] are very sophisticated, comprehensive, and complex.  It is abundantly clear . . . that [Super Lawyers does] not permit a lawyer to buy one’s way onto the list, nor is there any requirement for the purchase of any product for inclusion in the lists or any quid pro quo of any kind or nature associated with the evaluation and listing of an attorney or in the subsequent advertising of one’s inclusion in the lists.”
