About Master Aluminum & Security Shutter Co.

Mario Calleja is president and founder of the Master Aluminum & Security Shutter Co. His experience with shutters began as an installer for a very large national shutter manufacturer in 1981. In 1986 Master Aluminum was formed as a local manufacturing and retail company. Like many others, they manufactured their own roll shutters and accordion shutters for sale and installation to local customers. Since product quality at all stages was always a primary concern, Mario maintained a “hands on” involvement in sales, engineering, product development, manufacturing and especially installation.
