Providing GSA-Approved Services for Over 20 Years

In 1995, Alliance Detective & Security Service, Inc was awarded our first federal contract for security services when we took on the federal building at Augusta, ME. At the time we won that contract, it was set aside for small businesses.


Following the devastating attack on the federal building in Oklahoma City in April 1995, the General Services Administration consolidated the New England region into one contract and Alliance was chosen as a subcontractor due to our status as a small business and as a woman-owned business.
