The Quinlan Story

Our company was founded by Bob Quinlan in 1977 like many start-up companies, in a garage and on a part-time basis. After only a short time Bob resigned his full time position and devoted his time solely to building his dream of a locksmith business. With the help of his wife, Judy, and his friend, Roy Miller Sr., he opened a 200 sq. ft. shop in South Holland, IL. After only a year the business was forced to expand to a 1,200 sq. ft. location.

Along with Growth Comes Change

In 1986, Bob's son, Steve joined the company. In their efforts to provide a higher level of security, they started Quinlan Alarm Systems and expanded to electronic security services to push the business forward. Today, Quinlan Security Systems has a staff of 10 and operates out of a 4,800 sq. ft. facility in Mokena, IL.

Service is our Greatest Asset

With a strong reputation in quick response, quality, installations and top notch service, Quinlan is "Protection you can trust". Quinlan's attention to detail and designs that make sense separate us from the typical sales approach. Quinlan and its employees truly care about getting the job done right.

With Thanks to our Clients

Building a business with a reputation for quality service as well as supplying effective security for commercial, industrial, and residential customers has been vastly fulfilling for Steve and the Quinlan team. We take pride in our work and our reputation for excellent service and thank everyone who has come to us for help with their security needs.
