I spent the day at the Patterson Technology Center in Effingham Illinois. The facility is gorgeous and amazing.
Many things impressed me; one of the most significant was the obvious commitment to customer service. They had rooms full of old computers, printers and x-ray machines just so they could duplicate conditions in various dental offices and troubleshoot problems.
The center is not just for computers and Eaglesoft but also supports Cerec. So they have a room full of old Cerecs to use for support.
They also have a large call center with room for considerable expansion and are committed the keeping support in the US.
