Greg Antor
After years of service in the fire service and a deep passion for training and teaching, my interest in firearms grew from curiosity into commitment. While I had long respected firearms, it wasn’t until early adulthood—after an attempted break-in at my home—that I realized the responsibility of taking personal protection into my own hands.
That moment became the catalyst for purposeful training. Through consistent practice, professional instruction, and mentorship, I developed a strong foundation in firearm safety, weapon fundamentals, and concealed carry. This path led me into instructing others in basic weapon fundamentals and CCW training, with a focus on safety, confidence, and real-world application.
I have since continued to expand my skill set into tactical medicine, security operations, and executive protection, always seeking higher standards and broader experience. Learning never stops—whether from seasoned mentors, fellow instructors, or the students I train.
My goal is simple: to build confident, capable, and responsible individuals through disciplined training, practical knowledge, and a mindset rooted in preparedness and accountability.
