Our Core Investigative Services
Surveillance
Surveillance is one of the most powerful tools in an investigator’s arsenal. Whether it's a cheating spouse, suspicious employee, or ongoing fraud, we discreetly monitor and document behavior to provide real-time evidence you can trust.

Our investigators are trained in both static and mobile surveillance and use high-definition video, photography, and GPS tracking (where legal) to build a clear picture of the subject’s activity — all without detection.
Common uses of surveillance include:
- Infidelity investigations
- Workers’ compensation fraud
- Insurance investigations
- Workplace theft or misconduct
- Custody disputes
Background Checks
In a world where trust is increasingly critical, knowing who you’re dealing with is essential. We conduct detailed background investigations to help you make informed decisions about:
- Potential employees or contractors
- Business partners and associates
- Significant others or domestic partners
- Tenants or service providers
We access verified, up-to-date data that includes criminal history, civil litigation, employment verification, address history, and more — all compiled in a legally compliant, confidential report.
Records Research
Records research is key when you need documented proof of someone’s past — or lack thereof. Our team combs public and proprietary databases, court filings, property records, and other archives to uncover:
- Legal history
- Property ownership
- Marriage and divorce records
- Bankruptcy and liens
- Corporate affiliations
This service supports everything from legal proceedings to due diligence checks and is often paired with surveillance for deeper context.

- Attorneys and law firms
