Founded in 1949 in St. Louis, Whelan Security has enjoyed a rich heritage of service excellence for 66 years.  While other security companies have merged, consolidated, downsized or sold, Whelan is still owned by the same family and driven by the same principles of integrity and conservative business ethics that date back to founder James T. Whelan.  For the last decade, we have been one of the fastest growing firms in the industry, and yet our growth remains organic - one client and one employee at a time.  Technological innovation and a performance-based business model epitomize our forward thinking organization, and yet we offer the historical stability of a company that has been in business since 1949.  A credentialed and experienced leadership team promotes our conservative business values and employee-centric culture.  These are just a few of the characteristics that describe Whelan Security.
