Our father Dennis C. Williams founded SALEM SECURITY INC. over thirty years ago. While serving with the Chicago Police Department in the late 1960’s, he became frustrated after hearing about burglaries he considered preventable. As a favor to family and friends, he and our mother Ruby began installing security systems. Word spread quickly. Astounded by the high demand for his security systems, Dennis resigned from police work in 1977 to devote full attention the company.
