History and General Information

Joe Pellak began his career in 1966 as an alarm apprentice with Alarm Systems Inc. in Rockville, Maryland.  In 1976 he joined Wells Fargo Alarm Services in Washington, DC. as a security installer.  During his ten-year career with Wells Fargo, Mr. Pellak was promoted to area foreman, then to operations manager, where he was responsible for the day-to-day operation of the central station, service and installation department for Washington's second largest alarm company.  In 1986, Mr. Pellak left Wells Fargo and formed Security Engineering.  During  the early years, Security Engineering provided their services as contractors to install and service IDS systems for government agencies, government contractors, and other high-tech industries.  Today, our services also include the installation and service of CCTV and access control systems.

Our business philosophy is simple:  We only serve a limited number of large customers so we can provide the greatest quality of service.  When you contact or call our office, you will speak to a familiar voice that remembers you and cares about your needs.
