Relationship: Fellow lawyer in community
Walter Costello is a highly respected, recognized giant in the legal community, both in MA and nationally. Identified as one of the Best Lawyers in America since 1978, he is the epitome of the principled, gracious, yet zealous advocate that every lawyer should emulate. He is extremely knowledgeable in the law, and has been a mentor to many lawyers, including me. And I count myself very lucky for that privilege. His advice and counsel are constantly in demand and sought by seasoned attorneys, bar leadership, and jurists alike. He is honest and supremely ethical by nature, he is truly a lawyer's lawyer in the real sense of the term, and I cannot endorse him highly enough.
