“To say Atlantech Online is one of AOTA’s most strategic technology partners is an understatement. They have played a pivotal role in helping us succeed with at least 3 major projects that are often some of the most complex an organization can undertake. In a span of just a few short years, we have accomplished a data center migration, phone system implementation, and an entire office renovation. The entire team at Atlantech has been there through all of those projects providing us with valuable guidance, project management, and simply honest and excellent work.”

Juan Sanchez, Director of Information Technology, American Occupational Therapy Association, Inc.

“I have been a loyal customer of Atlantech Online, Inc. (“AOI”) for many years now. It is critical to my business that we have extremely reliable connectivity services and AOI delivers. And, if an issue does arise, AOI’s customer service is some of the best I have ever experienced."

Michael Cogan, Esquire, Michael R. Cogan, P.C.

“Knowing that your 24x7 engineering team is managing our router and firewall lets me focus on growing my business instead of managing technology.”

Tony Crisalli, President, L&R Floors

“Atlantech Online is an exceptional telco provider. Their service is reliable and their customer service is top notch. Our previous carrier could not provide SIP trunking to us quickly or cost effectively as Atlantech.Choosing Atlantech is a decision I do not regret. Atlantech Online has made my job as telecommunications manager a lot easier than in the past. There is no reason not to consider Atlantech Online as a CLEC. “

Barbara O’Donnell, Assistant Chief ITI Division, M-NCPPC

“Great product. Excellent customer service. Fast turnaround for requests. I have been using Atlantech Online’s colo and Internet connectivity services for three years now and have not experienced any issues. I would highly recommend their product offerings.”

Art Schertzer, IT Infrastructure Director, Radio One

“We have been long-time customers of Atlantech Online’ s internet services. Three years ago when we decided to research and compare VOIP providers, we ultimately settled on Atlantech’ s Shoretel solution to best meet our needs. The excellent service we received through the years as our ISP was part of the reason we chose them. They continued to provide the excellent service we expected during the VOIP installation and now continuing support of our new VOIP phone services. Atlantech Online’ s services continue to be top-notch.”

Jennifer Trumble, Operations Manager, Walsh, Colucci, Lubeley & Walsh

“As a Federal IT service provider, we contracted our internal Internet Connectivity and telephone services to Atlantech Online. They provided a smooth transition from our previous Internet/ Phone provider. Reliability is crucial in our line of work, and the quality of their performance has consistently met and exceeded our expectations.”

Rodney G. Hawkins, President, Washington Technology Group, Inc.
