Before joining the Department of Justice, Lucy clerked for the Honorable Michael D. Wilson, who was an Associate Justice of the Supreme Court of Hawaiʻi at the time. During law school, Lucy served as a Case Note Editor for the University of Hawaiʻi Law Review and was an oralist on the Philip C. Jessup International Law Moot Court team.

On being part of the Law School, D Dangaran shared, “I am thrilled to be joining a Native Hawaiian place of learning. I was born and raised on Oʻahu and have tried to bring Hawaiian values with me throughout my career. Coming to Richardson feels like returning to my roots and digging in deep to grow intellectually and support the future lawyers of Hawaiʻi as they, too, take Hawaiian values into legal practice on the islands and beyond.”
