David has a demonstrated history of working in the security, public safety, emergency management, and public education industries. Before transitioning into the private sector, he served for 31 years with Southern California law enforcement and was a first responder to the 9/11 World Trade Center attacks in New York city. His distinguished public service career provided a strong foundation for building trust and solving complex challenges.

Following his law enforcement career, David earned a reputation for delivering exceptional customer service, developing strong client relationships, and achieving consistent business growth with sales and business development roles with integrator American Integrated Security Group (AISG) and with Motorola’s A&E group and Federal Government Division/DoD.

David has a bachelor’s degree in criminal justice from California State University, Long Beach. He’s also a board member with Optelligent Market Solutions, which offers services tailored for companies venturing into the US physical security market.
