Tom Grisham - CCIE #1767 Emeritus

 
 
Welcome to my professional biography, CV and online resume’.  I have had the great pleasure to help create many communication solutions across a unique set of industry’s and environments during my career.  I hope you find the information helpful to see how my company can bring a history of success to your current business needs. 


I founded TRCN, LLC in 2003 as a premier independent communications solutions provider.  The strength of TRCN is the combined industry experiences and skills from best talent that I’ve come to know over the years.   Technologies change, adapt, morph at a faster pace than ever before.  It is impossible to find a resource with 5-7 years experience in many areas.  But with TRCN you can find a team that brings direct applied experience to every (Bit, Byte and Baud) of the underlying infrastructure components.
