Investigative Services

Fraud and Insurance

Fraud, insurance, and embezzlement scams can be very costly to those being deceived. Our investigators use background checks, surveillance, asset checks, and bank locates to discover wrongdoings. All evidence is discovered professionally and legally within the terms of California law so it may be used in court.


These investigations involve individuals and their personal situations. We understand how sensitive these situations are as individuals generally do not want their issues being exposed to the public. We use the utmost discretion and care in these cases. Whether you are looking to expose infidelity, find a missing loved one, or are involved in a child custody case, we have the resources to tackle the most difficult domestic investigations.


We gather evidence and uncover the truth for those involved in civil matters. We work with individuals and legal teams to investigate civil situations that are going to trial or plan to be settled outside of the courts. These investigations include personal injury, workers compensation, and abuse cases. We conduct witness statements, gather physical evidence, and pull digital records to provide the necessary evidence for your case.
