INVESTIGATIVE SERVICES "Focused, Credible and Actionable Investigations".

GRI INVESTIGATIONS  is a leading provider of investigative services for private clients, law firms, corporate legal counsel and insurance companies. Unlike other private investigators that offer a wide-range of services, we specialize in conducting investigations dealing with Civil, Family Law and Domestic issues. Consequently, our typical client is someone that requires evidence to support a position and/or argument in their lawsuit or legal action. To that end, our investigators utilize legal and ethical investigative techniques to gather evidence that stands up to scrutiny in adversarial legal environments. 

Our main goal is completing results-oriented and transparent investigations. Each investigation that we take on is designed specifically for each client based on their goals and investigative objectives. After a thorough needs analysis is completed, we submit a case proposal which outlines our fees and costs to complete the investigation. In some cases, we make a recommendation not to proceed with an investigation, because of potential legal issues or low result probabilities. 

As always, we recommend that you contact a qualified attorney to obtain legal advice on the specific evidence or information that would benefit your legal case before you seek the services of a private investigator. 


In California, there are thousands of lawsuits that are filed every year. At times, attorneys or their clients require the professional services of a licensed investigator to obtain evidence or information for their legal cases.
