About
Where today's headlines
meet real-world experience.
Turning headlines into understanding — one story at a time.
Dan enlisted in the U.S. Navy in 1994 and served until 2003, including four years as an instructor at the United States Naval Academy. He joined the FBI the same year and spent the next two decades hunting the country's most dangerous criminal organizations.
As an FBI SWAT Tactical Operations Team Leader and Crisis Management Coordinator for the Newark Division, he led tactical operations and managed multi-agency response to high-stakes incidents. He spent 15 years on the gang unit and four on domestic terrorism, working RICO cases against skinheads, cartels, and transnational criminal organizations.
In 2019 he became a founding member of Joint Task Force Vulcan, the FBI unit established specifically to dismantle MS-13 — work that took him from courtroom testimony to capturing a Top Ten Most Wanted fugitive. He retired from the Bureau in September 2023 and now serves as President and Co-Founder of Brunner Sierra Group, a forensic accounting and security consulting firm he runs with his wife Christine in Bozeman, Montana.
He holds a Master's in International Security Studies from the University of Arizona, a current Top Secret/SCI clearance with polygraph, and is a native Spanish speaker with deep family and professional roots across Latin America.
Areas of expertise
What Dan is known for on air.
The topics he's booked to break down across CNN, Fox, NBC, Univision, Telemundo, BBC, and every serious podcast in the space.
Latin American Geopolitics
Venezuela, Mexico, Argentina, Colombia, Chile — reported in fluent Spanish with on-the-ground sources from his FBI career.
Fentanyl & Drug Trafficking
The Sinaloa–Hells Angels Canadian fentanyl pipeline, precursor flow from China, and the public-health crisis at every U.S. border.
FBI Operations & Culture
SWAT tradecraft, RICO prosecutions, crisis management, domestic terrorism, and the politicization debate — from a 20-year insider.
High-Profile Cases
Kidnappings, school shootings, attacks on federal buildings — fast, accurate, on-camera analysis of breaking national stories.
Cybercrime & AI Threats
Deepfake voice fraud, "pig butchering" crypto scams, sextortion, Scattered Spider, and the "764" cult preying on kids online.
China & National Security
Chinese coders inside Pentagon cloud systems, infrastructure attacks, Taiwan, and the data-collection war shaping U.S. policy.
Crisis & Personal Security
Hardening soft targets, active-shooter response, home-invasion intelligence, and the playbook he wrote running FBI Newark crisis ops.
Mexico is on the brink of civil war. They’re not just into fentanyl and meth — they steal oil from Pemex and sell it. They have extortion operations around the country.
Television & news
On-air commentary in English & Spanish.
Dan appears regularly on U.S. cable, network news, and international outlets — breaking down cases in fluent English and Spanish. Univision, Telemundo, Mega TV, BBC, and networks across Spain, Argentina, and Chile.
