Mary Parker, president & CEO of Atlanta based ALL(n)1 Security Services is the only nationally-certified African American female owner of a full-service security firm in the country. She started the business in 2001 after leaving another security firm. Now, thanks to contracts with both private and public clients, the company claims more than 200 employees and revenues that Parker says will top $10 million next year. ALL(n)1 provides services ranging from uniformed security guards who patrol construction sites, stores, corporations and other facilities, to access control, remote surveillance and alarm systems, to traffic control and employee background checks. The firm has worked special events such as sports events and concerts, and done jobs for companies like Atlanta Gas Light and clients such as Hartsfield-Jackson International Airport. The Georgia Minority Supplier Development Council recently honored Parker with its Supplier of the Year Award, while the Atlanta Business League presented her with its Outstanding Achievement Woman of the Year Award.
