We have been a customer of Innovative Systems, Inc. since 2006. Our business has grown substantially since then due in no small part to the efforts of the staff at ISI. Some of the words I would use to describe the people of ISI include:
Their recommendations for building, upgrading and securing our systems have always been appropriate for our needs. They deal with and resolve problems quickly; and when they don't know answers; they are able to research and find them in short order. Finally, they are able to translate "geek speak" into language I understand.
I would have no concern recommending ISI to any organization considering them for technical support.
