Learn More About Us

We have over 30 years of experience in the IT/Computer and Consulting Industry. We've worked with some of the largest and most complex networks not only in Arizona but across the country. Our customer's satisfaction is our number one priority and we will leave no stone unturned to make sure you are a happy customer.

Another one of our priorities is to provide quality solutions at a fair price. So many larger "partners" bill over $250.00/hour for service and consulting. We feel this is exorbitant and in most cases, our hourly rate is less than half that of larger "partners". We can accomplish this by working smarter rather than harder.

Further, we want to work with your business not just for your business. It is our goal to make technology work for you, increase your productivity and ultimately your success. By doing so, we believe we are building relationships that will stand the test of time.

What our customers are saying about us:

  • "Excellent customer service. Dave addressed our needs and got us back up and running in no time. It was a pleasure working with him. We will definitely call again" -- Office Manager, Storage Facility
  • We were referred to Dave by our former IT guy. He came out and discussed all of our options with us and even took care of a few issues while he was here. Very professional and fast too. As a new custiomer, he even gave us a new customer discount" -- Managing Director, Hotel Chain
  • When our internet went down, we called GNSAZ.COM. Dave helped immediately over the phone but when that wasn't working, he came right out. He identified our provider was the issue and even worked with them to resolve. Great Job. Thanks Dave! -- IT Director - Credit Union
  • We hired GNSAZ to do a network assessement. The deliverable documents were incredible. Very detailed and informative. Dave's recommendations helped to resolve several issues we'd been having for many years. He even recommeded a cloud based phone system to replace our aging 10 year old system. Great work Dave! -- IT Manager, Arizona based Health Care Company
