Celebrating 65 Years as a Contract Security Company

Thank You

Thank You for 65 Outstanding Years

In 1949, Jim Whelan started a small contract security company in St. Louis, Missouri. Sixty-five years later, Whelan Security has quietly grown to become one of the largest contract security companies in the United States. Although our success is due in part to the phenomenal support of our esteemed clients and trusted partners, the growth of our organization is really a testament to the incredible loyalty, dedication, and passion of our employees who provide world-class service to our customers on a daily basis.

Thank you from the bottom of our hearts!
