About
Hello. My name is Mark, and I own MZ Security Consulting. Our veteran-owned consultancy specializes in public and physical security, risk/threat assessments, and security awareness training. Our goal is to help safeguard people, property, and assets from harm caused by physical events.
As a retired U.S. Navy veteran with over 27 years of experience, I understand the importance of protecting life above all else. My military experience has given me hands-on skills in decision-making, self-awareness, situational assessments, and psychology, which I will use to provide you with quality, realistic training.
Thank you for registering for our course. I look forward to hearing from you soon!
