Curley was previously chief of the National Security Law Division for the Army's Office of The Judge Advocate General.

Curley is just the eleventh marshal in the Supreme Court's history. The first was Richard Parsons, who served from 1867 to 1872. Most Supreme Court marshals have served for much longer, such as the previous marshal, Pamela Talkin, who served from 2001 to 2020.
