Bio

B.S., MIS
CCIE Collaboration #17577

I have worked for a top 100 home builder in Lexington, KY since 2001. In that time, both the company and the network have grown tremendously. In June of 2004, we moved our headquarters location and used the opportunity to deploy IP Telephony/Unified Communications. I posted several questions to the NetPro forum after our implementation and began regularly reading and posting to the forum in September of 2005. I've found the knowledge that I've gained from NetPro to be invaluable and the opportunity to help others very rewarding.
