Diversified Risk Management, Inc. was established in July 2002 by co-founders Patricia A. Kotze and George J. Ramos, Jr.

The executive management team has operated in 43 U.S. States, North America and abroad. Evidence-based investigative interviews are DRM, Inc.’s hallmark. Shortly after establishing its corporate investigative services division in 2002, DRM, Inc. introduced a new division providing employment background screening services, drug testing and pre-employment physicals.

In 2005, DRM, Inc. merged with Allied Management Resources, Inc., a boutique corporate investigation and security consulting firm established in 1996 by Kent Perkins. Kotze, Perkins, and Ramos had worked together previously at Confidential Management Services, Inc. in the early 1980’s. The firm acquired Kent Perkins’s stock upon his retirement; he remains associated, however, as a consultant.
