California Investigation

Investigations in Northern and Southern California

California Private Investigator, Filley and Associates conducts investigations throughout Northern and Southern California.  Our offices in San Francisco and Marin provide San Francisco Bay Area Private Investigator services, but we also provide California investigation services throughout the state.

Our operatives handle cases of all types in California.  Depending on case requirements, we either travel to the location of the investigation, (San Francisco is a one hour flight from Los Angeles.) or we use our extensive network of trusted Southern California investigators to handle portions of the investigation.  

Contact us to discuss your case.
