Experience & Expertise

I started as a computer technician covering a variety of different fields including IT configurations, desktop support, marketing, and building customer relationships. As my career has progressed, I have moved my focus to Routing and Switching while also leading 802.1x deployments through Cisco Identity Services Engine.


  • Cisco Certified Network Associate (CCNA) - Routing & Switching


One of the main things I love about NetCraftsmen is the family bond that all of us share. It is incredible to work with so many intelligent people who are willing to go out of their way to help make everyone else around them better.


In addition to working with some of the top names in the industry, my favorite part of the job would probably be the opportunity to meet so many different people and environments at different client sites. It seems no two clients are the same, so it is nice to be able to get diverse hands on experience.


On the weekends I enjoy playing golf as much as the weather permits in addition to being a major football fan. When the weather isn’t tolerable, I play the drums and enjoy spending time with my girlfriend and two dogs.
