For nearly 25 years, Eric Miller served as a Special Agent with the United States Department of Justice. He worked in some of America’s most volatile regions, conducting undercover operations, discreet surveillance, and complex criminal investigations that helped put violent offenders behind bars. Following the September 11, 2001, attacks, he was selected for an elite federal team to execute the TOPOFF2 Nationwide Terrorist Threat Response. He was later deployed to New Orleans to combat surging gang violence, and he then advanced to become a Supervisory Special Agent and Branch Chief, where he designed and led an award-winning national initiative that dramatically reduced government waste.

After a very distinguished Federal career, Eric transitioned to the private sector, working for several years with Valley Investigations and Ethos Risk Services before founding Miller Investigations, LLC.

This 30-year history of high-level experience allows Eric to deliver every case with exceptional skill, discretion, and professionalism. At Miller Investigations, your peace of mind and results are always our top priority.
