    Hard Hitting, High Talent Litigator, Thinks Well on her Feet
    Kathryn is a seasoned, well experienced and hard hitting litigator who can see the forest through the trees. Kathryn is all about results---getting you through your case on time and ideally under budget. She tells the truth and will not sugarcoat things when issues go against you and why. In the court room I found her to be not only exceptionally well prepared, but also lightning quick on her feet when fielding questions from the judge or when engaging live witnesses on the stand. Bottom line you've got a talented court room lawyer here, who also is a great writer and communicator. These are critical skills to getting your case resolved, ideally without a trial. You are in good hands with Kathryn from start to finish. -Craig
