M Sauer Security Company begun in the security business back in the 50’s

in Memphis, Tennessee, as an ornamental iron manufacturer. We

transformed the much-needed window and front door guards into works of

art via the intricate patterns we welded together.  An example of our work

still exists at the front of Elvis Presley’s Graceland Mansion. The front gate,

designed with a guitar and music notes, was created by our company.

    A division was opened in Baltimore, Maryland during the summer of 1976

at a time when security was transitioning from physical, to electronics. In keeping with the times, we begun installing burglar alarm systems, cameras, and electronic entry / access control systems.
