IT Professional
Lincoln, Nebraska


I have been part of the Information Technology field for twenty years.  I have had the opportunity to see and support a wide range of hardware and software.  I have seen technology and business practices change drastically in the IT field during this time.  This industry is very fast-paced and always changing.  To experience how technology has affected the way people do business over fifteen years gives one a unique perspective on how to use technology to improve business.  I spend a majority of my time in Microsoft System Center automating the process of operating system and software deployment to make it as fast and streamlined as possible.
