It isn’t at all surprising that someone with Justin Kollar’s values and background would find themself at home on the island of Kauai. On his first visit to the islands in 2001, he fell in love with the place and the people that we have all fallen in love with, and returned to Oahu to clerk for the Honorable Daniel R. Foley, who served on the State of Hawaii’s Intermediate Court of Appeals.

Justin realized the beginnings of his dream to build a home here when he accepted a position as a Deputy Prosecutor under former Kauai Prosecuting Attorney Craig A. De Costa.

He worked his way through Traffic Court to vehicular homicide cases and felony drug cases. It was because of his work in these areas and his reputation as a top trial attorney that County Attorney Alfred B. Castillo, Jr. offered Justin an opportunity — which he accepted immediately — to become the Kauai Police Department’s first legal advisor.

His work with the Police Department brought his understanding of the criminal justice system on Kauai full circle, making him the ideal candidate for Prosecuting Attorney. In 2012’s general elections, Kauai’s voters agreed by a wide margin. Justin was re-elected in 2016 and the community sent a clear message endorsing Justin’s values and vision for the Office.

Justin graduated from Boston University with a degree in History and Political Science. After working as a manager for a printing company with twenty employees, Justin made the decision to dedicate his life to public service. The best way to do that, he decided, was to study law — which he did at night while working full time during the day — at Suffolk University Law School.

While studying for the bar, he clerked in the Massachusetts trial court system and upon passing the bar, he worked as an Assistant Corporation Counsel for the City of Boston Law Department. His work there focused on litigation in state and federal courts concerning contracts, zoning and police misconduct.
