  • Scott John Terry

    I have known Stacey for many years and have referred several cases to her in the past. I have found her to be very competent, and I have always received excellent feedback from those whom I have referred to her. At times we have had mutual clients who required representation involving each of our respective expertise. I have always been impressed with the high quality representation she provides her clients and I will continue to refer with confidence.
