Background Checks/Credit Checks

Excell Investigations can run background checks and credit checks for Los Angeles businesses, property managers, leasing companies, attorneys, and individuals. These background checks are used to verify or check someone's qualifications, academic accomplishments, driving record, employment history, criminal history, past lawsuits, past insurance claims, liens, business listings, fictitious business names, affiliations, and more. To effectively gather this information on existing or prospective employees, business associates, tenants, neighbors, witnesses, claimants, significant others, spouses, family members, and others, one of our licensed investigators will leverage our extensive public records database, federal and military records, and more. Call today.

Criminal Background Checks

Excell Investigations also provides comprehensive criminal background checks. Los Angeles attorneys, employers, insurers, private security firms, schools, and even loved ones can benefit from having a licensed, seasoned investigator conduct one of these exhaustive checks that uncover convictions as well as arrests, bookings, arraignments, and charges. Our criminal background checks are reasonably priced, completed in a timely manner, and can go back as far as 15 years (or up to 7 years for pre-employment screenings).

Polygraph Services / Lie Detection Testing

At Excell Investigations, we have years of experience administering polygraph (or "lie-detector") tests in Los Angeles. Our polygrapher is professional, discreet, and certified by the California and National Polygraph Associations. Performed at our offices and reasonably priced, our polygraph tests are generally used to determine the trustworthiness of an individual, especially in situations when there's no tangible evidence available or conflicting stories. While usually not admissible in court, they can be very effective in confirming or discounting the claims of a spouse, romantic partner, employee, or other individual.

Counter-Surveillance

Excell Investigations is equipped to meet all kinds of counter-surveillance needs in the Greater Los Angeles area. With more than two decades of investigative experience, we are experts at observing, documenting, photographing, videotaping, and investigating individuals, businesses, and associations. Counter-surveillance is a service that involves surveilling someone you think is following, monitoring, stalking, or spying on you, as well as using the latest in counter-surveillance technology, such as bug sweeping and eavesdropping detection. We also specialize in anti-stalking counter-surveillance which can consist of covertly following and investigating a suspected individual, taking detailed notes of their whereabouts and activities, performing a threat assessment, and providing detailed, professional reports, all of which are particularly important for those in the process of obtaining and/or enforcing a restraining order, or looking to ensure their workplace or home is a safe and secure environment.

Fraud Investigation

At Excell Investigations, we offer our expert fraud investigation services in Los Angeles at a great value. Our fraud investigations are usually related to identity theft, internal theft, embezzlement, and similar cases involving fraudulent activity. Using covert surveillance, polygraph testing, employee interviews, undercover investigators, computer forensics, and more, we are often able to collect evidence that helps identify a suspect(s) and convict them. Call today to work with a locally based, licensed investigator who can help you tailor a fraud investigation program for your needs and budget.
