As a Certified Medical Investigator, Behavioral Technician, Nationally Certified Psychiatric Technician, Certified in Homeland Security,  we offer Death Investigation, Substance Use testing, Medical Management Genetic reports for correct drug prescribing, and are experts in Behavioral Health including Mental Health and Substance Use Disorders. We have worked twelve California State death penalty cases at the federal level - both guilt phase and mitigation.

As the authors of "The Murder of Marilyn Monroe: Her Lips Were Sealed Until Now" we have documented proof of the murder of Marilyn. Available on Amazon and Barnes & Nobles.  Our quest is to change her death certificate to homicide. Our interview with a retired LAPD OCID agent revealed what really happened. Documents are included to support our claims of corruption, false exculpatory information produced, along with who and how she was murdered! 

We have the ability to collect information from targets that reveals plans, intentions and capabilities of the opposition and in turn provides a solid foundation for the decisions and actions we perform. As a result of our insightful operative procedures, we are able to conduct a thorough analysis to provide imminent warnings and the same gives us the opportunity to convey information to the decision makers charged with protecting and advancing the interest of the United States of America.
