The Trainer
Mary Martinez
Founder, Lead Instructor — Sentinel Academy. Twenty years of security operations across corporate, government, and executive protection assignments.
Mary founded Sentinel Academy after two decades watching the same problem repeat in every operations center he ran: officers arriving on shift with credentials that didn't reflect what they actually knew. Sentinel was built to close that gap with monitored, accountable training — the standard every client deserves.
