Chris likes to sum up his role in two words: Problem Solver.  Every position Chris has ever held is anchored by the fundamental skill of grasping complex problems and finding common sense solutions.  Chris started working for a small technology consulting firm in the Tampa Bay area right out of college.  He quickly added skills to his portfolio, starting with desktop and server support, until he found his passion for networking.  

He joined the team at SunTrust Bank, progressing from field network installations to Network Architecture in the course of 4 years.  During his time at SunTrust, he also became the primary Security Technology architect for the bank. Projects at SunTrust included migration of 2000 locations from Frame Relay over ATM to MPLS, architecture and implementation of two complete Data Center migrations, and the development of a fully fault-tolerant Extranet (partner) network.  Subsequent to SunTrust, Chris joined e*Trade Financial, Fiserv, Genuine Parts Company, and ultimately Horizon River Technologies.
