We believe in building long term relationships that earn your trust.   Our protocol is to consult with each client prior to beginning any investigation to identify the proper approach. We like our clients to know what we will be doing and when we will be doing it.  We are always up front with an estimate of the total cost of investigation, so there are no hidden surprises.   


We Provide the Information. You Make the Informed Decision.


Our clients are private individuals, large and small corporations, landlords, attorneys and their law firms.  We are sensitive to our clients' needs. Many of our clients have never hired a private investigator and are unsure as to how to proceed.  This is where our expertise comes in; we will plan a course of action with you.

Browse our site and have confidence when you use our services.  Your needs will be our number one priority.


Bottom Line; Our licensed and experienced investigators provide investigative and situational solutions with complete discretion and professionalism to every client! We use undercover operatives, advanced investigative techniques, high-tech surveillance operations, and plain old street smarts & desk work.
