Basis for Inclusion: Letitia A. Long holds documented governance roles at both T-Mobile US Inc. and Parsons Corporation — two companies in the Patriot University accountability knowledgebase. At T-Mobile, she holds the unique designation of “National Security Director” — a formal governance role created as a condition of the Sprint merger approval, establishing a dedicated board-level liaison between T-Mobile’s governance and U.S. national security requirements. Her concurrent board role at Parsons, a major defense and government services contractor, creates a cross-sector governance profile of national security significance. This cross-board profile is consolidated per Patriot University’s deduplication rule. This profile documents the factual governance relationships, not the subject’s personal political views.

Subject Classification: Private Citizen / Corporate Director. Board memberships are matters of public record (SEC filings, proxy statements). This profile documents only governance roles and their connection to documented corporate activity.

Biographical Overview

Letitia A. Long is one of the United States’ most senior former intelligence officers. She served as Director of the National Geospatial-Intelligence Agency (NGA) from 2010 to 2014, making her the first woman to lead a major U.S. intelligence agency. Before the NGA, she served as Deputy Director of the Defense Intelligence Agency and held numerous senior positions across the U.S. defense and intelligence community throughout a career spanning more than three decades.

After retiring from government, Long became active in corporate governance across the defense and technology sectors. Her designated role as T-Mobile’s National Security Director is unique in U.S. public company governance — it was established as a formal condition of the DOJ and FCC approval of the T-Mobile-Sprint merger to ensure ongoing government oversight of the combined company’s management of Sprint’s national security-sensitive network assets.

She is a member of the Intelligence and National Security Alliance (INSA) board and the National Board of Trustees of the American Red Cross.
