MCLEAN, Va., January 27, 2026 (Newswire.com) - Executive 1 Holding Company today announced that Vice Admiral (Ret.) Andrew J. Tiongson, U.S. Coast Guard, has joined its Board of Advisors. A retired three-star officer with over 36 years of leadership experience, Vice Adm. Tiongson most recently served as Commander, Coast Guard Pacific Area, responsible for Coast Guard operations spanning the Indo-Pacific, Arctic and Antarctic regions, and to the coast of eastern Africa, while concurrently serving as Commander, Defense Force West in support of the Department of Defense and Combatant Commanders. Tiongson will serve on the Board of Advisors for both CORAS.ai and HumanTouch, two companies managed by EX1, driving Agentic AI, decision intelligence, and digital modernization for defense and civilian federal agencies.

"Andy has led at the scale and complexity our customers operate in every day-where decisions must be made quickly, with accountability, across joint and interagency teams," said Moe Jafari, CEO of Executive 1. "His operational perspective, experience managing multi-billion dollar security budgets and audits, and strategic stewardship will be invaluable as we optimize agentic AI productivity, readiness, and decision intelligence across the Armed Forces."

As CFO, he helped drive enterprise accountability and achieved two consecutive clean, unqualified audit opinions- the first for any U.S. Armed Service.

"I'm honored to join EX1's Board of Advisors," said Tiongson. "In my experience, mission outcomes depend on a clarity-shared understanding of the operating environment, the resources available, and the trade-offs leaders must make. EX1 is focused on strengthening that decision advantage, and I look forward to supporting the team and its customers."

Throughout his career, Vice Adm. Tiongson served as a career cutterman with sea duty spanning five Coast Guard cutters and one U.S. Navy ship, including deployment in support of Operation Desert Storm as part of a Coast Guard-Navy exchange program.
