Built on a Career of Protecting People

Most security companies hire guards who took a weekend course. MT Security is led by someone who spent 15 years as a Chula Vista Police Department officer — making split-second decisions that saved lives.

Michael T. founded MT Security & Investigations in 2002, immediately after retiring from the Chula Vista Police Department with a decorated 15-year career. He didn't step away from service — he redirected it. The same discipline, investigative instincts, and community commitment that earned him three department awards now set the standard for every guard, every report, and every case we handle.

Unlike competitors who manage guards from a distance, Michael remains personally involved in every client engagement. New clients speak with him directly. Sensitive investigations run through him. When something goes wrong on your property at 2 a.m., you're not calling an answering service — you're calling someone who has worked emergencies firsthand.

That difference is why organizations like Horne LLP, RealManage, Helix Charter Schools, and Lighthouse Baptist Church trust us — not just to show up, but to actually protect.
