John A. DeMarr, P.I. – Investigation Services
The California Private Investigation and Private Detective Firm
Since 1988, John A. Demarr, P.I., has been providing professional, licensed private investigation and private detective services, to businesses and individuals in California and beyond. Our clients include law firms, insurance companies, major corporations and small businesses.
We also provide services to private individuals. Our California-based private investigators and private detectives provide experienced, discrete marital infidelity investigation; spouse and nanny surveillance, and child custody monitoring. Our investigators have testified in court many times – and you should consider the value of an objective investigator’s court testimony presented to a judge and/or jury.
Our staff includes police-trained, seasoned professional investigators, document experts, interview experts, and industry experts in the credit, collections, lending, and legal fields. We are trained to deal with private investigation, process service, site security (commercial and residential) and all phases of private detective work.
Our investigators and support staff must pass rigorous criminal background checks. This ensures our clients that our investigators are qualified and reliable.
Our detective work and investigative work incorporate the latest technology. But our private investigators and private detectives use street-smart old-fashioned logic, shoe leather, effort and attention to detail to achieve results. Our technology extends our eyes and ears, but it does not substitute for tried-and-true investigative procedures, knowledge of our turf, and our experience. The results of our private investigation reflect this multi-disciplinary approach.
John A. DeMarr, P.I., is proud of our affiliation with the California Association of Licensed Investigators, the World Association of Detectives, the California Association of Legal Support Professionals, and the National Association of Professional Process Services – just to name a few of our professional affiliations.
When you become our client, we offer experience, training, technology, professional discretion and thoroughness to meet your needs.
We investigate online and offline. If you have a hunch, we can check it out and find the truth – as we have done for so many clients.
