MGI - recognized as a leader in security systems within New England for over 30 years. Established in 1964, Monahan & Associates was originally organized as a security company providing investigative and security guard services. In 1971, M&A closed its security guard division and changed its focus to electronics, becoming a full service installing company, offering CCTV, intrusion and fire alarm systems, and operating a 24 hour UL/FM approved central monitoring station ? one of only two independently owned companies in Massachusetts.In 1986 the UL/FM approved central monitoring station was sold and we continued to work in the security industry installing access control and CCTV systems. At the same time, our reputation, knowledge of, and strength in the security industry moved us into the consulting arena and that is where we find ourselves today ? almost 40 years later.You can rely on MGI for all your security needs.
