Because of my foundation in Cisco routing and systems, I have been able to build on those skills to become well-rounded in overall IT administration.

I have been a part of two separate data center moves, both physical to physical, as well as physical to the cloud. I have successfully upgraded to several different platforms, learning along the way. Because the world of technology is constantly changing, I am always learning about the latest innovations and processes. And while I have not done everything, my wide range of experience enables me to adjust and succeed in every project.
