Joe Diaz

President and CEO

Joe Diaz’s involvement with security and investigations dates back to 1975 when he began his law enforcement career as a uniform officer with the Miami Dade Police Department. A few years later, Mr. Diaz was assigned to the Miami Dade Police Homicide Bureau where he spent 10 years as a member of an elite task force investigating criminal groups involved in major narcotics related homicides and related crimes. Mr. Diaz investigated and supervised numerous cases of homicide, kidnappings, narcotics and weapons trafficking, public corruption, racketeering, police shootings and other criminal acts committed by major drug cartels. Some of Mr. Diaz’s duties in the joint federal task force included setting up safe houses and coordinating the protection and security measures for important witnesses and their families in the United States and abroad.

Mr. Diaz retired honorably from the Miami Dade Police Department and began a successful career in the private sector where his goals shifted from enforcing the law to providing security and investigative services to private clients and developing innovative concepts and quality control measures that consistently deliver the exceptional level of service that our clients expect and deserve.
