Background and Pre-Employment Investigations

When you need to learn the truth about someone, Pinnacle's New York Private Investigation service is your one-stop shop. Whether you are in Human Resources or a law firm we have a background investigation designed to meet your needs. Employment and educational verifications; criminal and civil background checks; marital issues; business relationships; summonses; liens; judgments; bankruptcies; associates; relatives; asset location (excluding banks or brokerage accounts); expert credentials and prior testimony; Politically Exposed Persons (PEP); and a host of additional information can be identified and verified.

Each situation is different and what may be needed in one case may not be important in another. The level of depth that you decide upon is nearly limitless and in cases where thorough vetting is a requirement it can include personal interviews of relatives, neighbors, associates, co-workers, employers, etc. With proper authorizations, court orders, or subpoenas, medical and personal financial information can be obtained or verified.

Our Long Island, Queens, Brooklyn, Bronx, Manhattan, Westchester, Rockland private investigators can accommodate your specific background investigations. We also offer out-of-state and international investigations, and specialize in New York State Banking Department applicant investigations.
