    Dr. William Lindsey, President - Lincom Wireless

  • I have been utilizing Techonsite for my IT needs for approximately 5 years. The firm recently implemented the upgrade of a new server and workstations for my CPA firm. The majority of the work to configure the new server and workstations was done via remote login to my network, therefore there was no disruption to my normal day to day operation. The final steps of the implementation was done on a weekend so when my employees came to work on a Monday, they had new computers that were operational and the same desktop display as their old computers. I chose Techonsite for the implementation because they have been responsive to my IT needs, they listen to the customer and do not try to oversell services, but they do offer recommendation for all IT needs. In summary, I would definitely recommend Techonsite to all business that need excellent technical support.
