  • Linda Medeiros Callahan

    Jacey Liu has changed the practice of DUI defense law in Clark County by fearless advocacy of her clients and exceptional knowledge of the intricacies of DUI defense. Her willingness to do battle has established her reputation as a fighter for justice for her clients and she garners amazing results because prosecutors simply do not want to do battle with her at trial. Jacey has a brilliant legal mind; her writing is impeccable in its persuasion and analysis. For several years she has contributed to the Washington DUI Practice Manual, published by Thomson-Reuters, and she recently authored eloquent briefing considered by the Washington State Supreme Court in a DUI appeal. I strongly endorse Jacey Liu.
