About Me

Back in the 1970s my father brought home our first computer.  This computer opened the world of technology to me.  I was programming before I was 12 years old and handling hardware soon thereafter.  I had the benefit of growing up with computers, having been involved with various technologies I have about forty years experience with Personal Computers.

In the early 1990s I was an electro-mechanical designer, doing drafting work for television transmitters, medical ultrasound machines, and ultrasonic cleaning systems.  At each position I held, I maintained the CAD systems and any related networks.  This was the beginning of my network experience.  When my wonderful wife was pregnant with our first child, we decided that the drafting field was too unstable and I changed careers to focus on technology.  The rest is history.
