The founders and executives of DRM, Inc. have been providing high level investigative services for more than 30 years. DRM, Inc. was established in July 2002 by founder, Patricia A. Kotze. DRM, Inc. offers clients a comprehensive suite of service offerings. With a longstanding reputation for discretion and competence, DRM, Inc. has handled thousands of matters involving employment, civil and criminal matters.

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 December 2004, DRM, Inc. introduced its compliance training division, providing employers with bilingual workplace training, including on-site instructor-led training and long distance eLearning via the Internet (online). The training division has since trained thousands of employees across the U.S. on a host of topics, including, but not limited to, sexual harassment (AB 1825) awareness, workplace violence prevention and substance abuse awareness. The training introduced an eLearning Internet-based platform which provides client access to numerous bilingual training courses, around the clock.

Subsequently, DRM, Inc. expanded services to include Computer Forensics, Executive Protection, and Domestic Investigation Services divisions.

In 2005, DRM, Inc. merged with Allied Management Resources, Inc., (AMR, Inc.) a boutique corporate investigation and security consulting firm established in 1996 by Kent Perkins. Ramos, Kotze and Perkins worked together 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.

DRM, Inc. has continued to grow, and in 2005 relocated corporate headquarters to Downey, California.
