Our comprehensive background checks utilize GLB, FCRA, and HIPAA-compliant methodologies to verify personal and professional histories. We employ multi-source verification for employment screenings, pre-marital investigations, and legal proceedings. Clients receive detailed reports with actionable insights for decision-making.
Surveillance Services
We conduct discreet video and camera surveillance operations using advanced equipment for insurance claims, fidelity issues, and legal evidence collection. Our investigators follow strict protocols to ensure admissible documentation while maintaining subject unawareness during monitoring periods.

Specializing in insurance fraud and financial abuse cases, we employ forensic techniques to uncover misrepresentations in workers' compensation claims, elder financial abuse, and identity theft scenarios. Our reports include evidence documentation and expert analysis for legal proceedings.
Child Custody Cases
We conduct thorough parental fitness evaluations and custody-related investigations using observational techniques and third-party interviews. Our findings provide objective assessments for family court proceedings while maintaining strict confidentiality throughout the process.
