Adam began his criminal justice career as a Special Investigator for U.S. Investigations Services, Inc. (USIS). He began this role only a month after the events of September 11, 2001. It was up to professionals like Adam to conduct in-depth background investigations on potential Air Marshals and determine their suitability for high level security clearances. Adam Quirk conducted thousands of face-to-face interviews with potential candidates. With an investigation completion rate that was consistently found to be in the top 5% of the entire country, Adam was regularly named the Top Investigator for USIS’ Minneapolis division. Because of Adam Quirk and the team he supported, many suitable Air Marshals were placed on flights to protect America from another terrorist attack.

In 2004, Adam Quirk began a new position as a Diversion Investigator for the Drug Enforcement Administration (DEA). Diversion Investigators are tasked with investigating the diversion of Schedule II - V controlled substances from their intended destination (e.g. legal distributors) or point of manufacture by criminal entities. Because of his existing investigation experience at the time, Adam was responsible for coordinating and leading long term investigations for the DEA and conducting on-site security assessments for drug manufacturers, distributors, narcotic treatment programs and other DEA Registrants. His efforts led the DEA to stop several physicians who were engaged in the illegal sale of prescription narcotics or abusing them themselves.
