Located in Northern Virginia along the Potomac River, Alexandria employs a great deal of people in the federal service and U.S. Military. Some of the area’s largest employers are the U.S. Department of Defense, United States Patent and Trademark Office and the Institute for Defense Analyses. The higher education facilitators are Northern Virginia Community College, and satellite campuses of Virginia Tech, and Virginia Commonwealth University. Points of interest include Cameron Run Regional Park, George Washington Masonic National Memorial, and the Mount Vernon Trail located between Alexandria and George Washington’s estate Mount Vernon. As the seventh largest city in Virginia the city has a population of about 140,121 and many businesses require the use of a high quality Alexandria outsourced call center and answering service. A live 24 hour telephone answering service is mission-critical for a small business that wants to continue to generate revenue after hours or during the day by way of a virtual receptionist. Having an emergency call center or answering service in the medical profession goes without saying, but having a local answering service as a small business owner is just smart business.
