  • Hal Harlowe

    Over the years, Ray and I have worked together on a number of cases. Every time I work with him, my respect for him grows. Ray is a lawyer's lawyer. He has an encyclopedic knowledge of the law, and is a tough, highly effective trial lawyer. Equally important, he is an enormously decent guy who is accessible to clients and respected by judges, opposing counsel and colleagues.
