After earning his Juris Doctor from Columbia in 1997, he served as an associate attorney at the international law firm of Morrison & Foerster in San Francisco. He then returned to Guam to accept a position as a research attorney for the Hon. Katherine A. Maraman, Judge of the Superior Court of Guam (now Justice, Supreme Court of Guam).
