ACC Telecom Voice and Data Network Solutions

Becoming increasingly aware of the growing business communications, telecom, voice and data cabling, and business phone system needs in the 1980’s, Mr. & Mrs. Hunt established ACC Telecom, headquartered in Frederick, Maryland (MD) to serve the Maryland, Virginia (VA) and Washington D.C. areas. ACC Telecom quickly grew to the area’s leader in business phone system installations, service and voice and data cable infrastructures.

In 1991, ACC Telecom relocated its headquarters to Ellicott City, Maryland. ACC Telecom’s fast-growing client base created the need for a more centralized location. In order to better serve the Baltimore, Maryland, Northern Virginia and Washington, DC corridor, Mr.& Mrs. Hunt selected Columbia, Maryland. The Columbia headquarters allows us to efficiently support the needs of our customers.
