Our experienced surveillance division conducts sub rosa investigations, civil and criminal background searches, trial preparation, and witness locating. We have recently added our Document Imaging Department with the partnership of SPI Document Imaging.

Our clients include insurance companies, third party administrators, and attorneys who insure and represent individuals and entities from both the private and public sector.

Licensed in California, our firm is centrally located in Fresno County. Our primary service area is the San Joaquin Valley stretching from Bakersfield to the south, to Sacramento to the north. We regularly travel to Southern California, California's Central Coast, and service many small communities in the Sierra Nevada foothills and mountains. We do travel throughout the state as needed, making every effort to prorate travel and mileage whenever possible.
