Our company has trusted Allied Technologies for phone and IT  services for over a decade, and we value their expertise and  reliability.  As part of our recent remodel, we are now using their digital signage product in our customer waiting areas, and  the response has been terrific.  

We have received many  compliments on the look of the signs, and the flexibility of the  product lets us easily manage the content.  

The process of  working with Allied on the product demonstration and   installation was a pleasure.

 We have relied on Allied Technologies Online for call center services for us and our tenants as well as cabling and voice and data services for over 15 years. Most recently, Allied has updated the lobbies in all of our office buildings with new digital signage displays to replace our old tenant directories. The feedback we have gotten on this upgrade has been very positive. Our lobbies have received a new modern look. We have also relied on Allied Technologies Online for business telephone systems and circuits. We would highly recommend them for any digital signage or telecommunications needs.

As the person who serves as an intermediary between customers   and ATO as the technical service provider, I have found their   service to be excellent. Our company has worked with ATO since   2014 and they have always been knowledgeable, kind and   responsive to our business needs.

 John, thank you so much for your assistance in getting our phones up and running.  Beth and I would have had no idea how to handle that situation on our own.  It certainly would have taken longer if we had tackled the issue left by the carrier.  You were professional and proactive, and we appreciate it.  It has indeed confirmed what we already believe about your firm.  You've been more than helpful, and we will certainly keep you as our go-to communication provider moving forward.
