    Mary is an exceptional litigator. She is always prepared and is a firm, but reasonable, negotiator. Mary also possesses the judgment that only comes with over a decade of experience. Whether adverse to her in litigation or advocating on the same side of a case, I have always been impressed with her legal skills. Few can equal her legal prowess.
