Mark Orr shares his extraordinary journey from serving three combat tours in Iraq as a United States Marine Corps radio and satellite communications specialist to becoming a Microsoft MVP, enterprise architect, and respected Microsoft security expert. He explains how military experience introduced him to networking, satellite communications, IP protocols, and infrastructure management before eventually leading him into Microsoft technologies, Microsoft Intune, Entra ID, automation, and cloud security. His career demonstrates how discipline, resilience, and continuous learning can create entirely new opportunities in enterprise IT.
