Soraya is a lawyer and former judge of the United States Virgin Islands Superior Court. She was the first woman and first Hispanic from St. Thomas to serve as a judge. She served not only as a trial judge, but also as an appellate court judge, hearing and deciding appeals from the Superior Court on St. Croix. During her years of judicial service and afterwards, Diase Coffelt promoted the improvement of the local judicial system through the development of an autonomous Virgin Islands court system, which included the establishment of its own supreme court. Her Master’s thesis, advocating the establishment of a supreme court, was used as a guideline by Virgin Islands lawmakers to create the Supreme Court of the Virgin Islands in 2004. Diase Coffelt also developed the V.I. High School Moot Court Competition in 1994, which is an annual, interscholastic competition for
high school seniors, with winners receiving college scholarships. The competition has been sponsored by the Virgin Islands Bar Association and the courts. In May, 2013, the Virgin Islands Bar Association presented Diase Coffelt with an award for her valuable contributions to the people of the Virgin Islands.
