Terry F. Lenzner founded the company in 1984 as an adjunct to his former law firm. IGI’s founding marked an expansion of the law practice Lenzner had begun a decade earlier through his use of an in-house investigative unit at Rogovin, Huge & Lenzner. Under his leadership, IGI has become one of the leading investigative firms in the United States, conducting a wide range of services for a diverse clientele of private and public entities and individuals.
Lenzner’s career began as an attorney in the Civil Rights Division of the Justice Department in 1964, where he was initially assigned to what became known as the “Mississippi Burning Case.” He also supervised the Department’s grand jury inquiry into events that occurred in Selma, Alabama in 1965.
He then joined the Organized Crime Division of the U.S. Attorney’s Office for the Southern District of New York, and was later named by Donald Rumsfeld to be Director of the Office of Economic Opportunity’s Legal Service Program, where he supervised 2,500 attorneys.
Lenzner later served as Assistant Chief Counsel to the Senate Watergate Committee that investigated the burglary and subsequent cover-up at the Democratic National Committee headquarters at the Watergate office complex. In that capacity, he authored and personally served the first Congressional subpoena of a sitting U.S. President.
Lenzner has conducted training sessions on complex investigations for the offices of the Inspectors General at several federal agencies and has lectured on that subject at Harvard Law School.
Lenzner is a graduate of Harvard College and Harvard Law School and was a member of the Board of Overseers from 1970 to 1976.
