About Sentinel Investigations
For over 25 years, we have been uncovering the truth for clients who need answers. Licensed, bonded, and trusted by thousands.
Our Story
Sentinel Investigations was founded in 1999 by Michael Harrison, a former FBI Special Agent with a vision to provide private citizens and businesses with the same caliber of investigative services he provided to the federal government.
What started as a one-person operation has grown into a full-service investigation and security firm with a team of experienced professionals. Each investigator brings unique expertise from backgrounds in law enforcement, military intelligence, corporate security, and forensic accounting.
Today, Sentinel Investigations serves clients across the nation, from individuals seeking personal answers to corporations protecting their interests to law firms building their cases. Our commitment to confidentiality, integrity, and results has earned us a reputation as one of the most trusted investigation firms in the industry.
