Daniel Oster is a Milwaukee-based security and public safety professional with more than 15 years of experience across law enforcement, aviation security, healthcare security, and large-scale training program development.
Daniel spent a decade in law enforcement — including aviation law enforcement, a specialized field requiring a distinct combination of regulatory knowledge, threat assessment, and operational precision in one of the most scrutinized security environments in the world. He later moved into the private sector, building security training programs from the ground up for large healthcare organizations.
His training background spans defensive tactics, crisis intervention, use of force, and professional communications — giving him a rare combination of technical instruction expertise and the behavioral foundation that makes training actually stick in high-pressure environments.
