My name is Rishard Chapoteau and I have been doing some form of computer networking since 1997. I started out more on the desktop side of things working with Banyan Vines. I was a Cisco MCSE which I kept for a few years but I eventually moved on to do more Cisco networking. I’ve had many Cisco certifications over the years, but I have never attained CCIE status. I’ve been both an employee and a consultant at many different locations. I’ve worked for Government agencies and private firms. Currently I work in the entertainment industry dealing with a lot of video and multicast.
