Nancy Swaim established The SWAIM390 COMPANIES in 2001 to conduct private investigations with comprehensive services for attorneys, financial professionals, business owners and private clients. In 19 years, SWAIM390 has handled hundreds of investigations ranging from locates and background checks to complex litigation, difficult subpoena service, asset searches and other complex information development.  Our mission is to produce confidential information with a practical, common-sense and cost and time-effective discipline.


SWAIM390 works primarily with attorneys and financial professionals with assignments pertaining to due diligence, litigation support and business intelligence. The firm’s Los Angeles based investigation team provides global support in investigations and accepts assignments by direct referral only.


Our professional memberships include CII, a global consortium and resource bank of private investigators and Highrise, a networking group of professional member/managers.
