I've worked for some of the largest fortune 500 companies, as both a Network Engineer, and later a cyber security engineer.  I've taken some really good IT training, and some awful training as well.

I have been certified with Comptia's A+, Network+,Security+(thier trifecta) as well as Comptia's CASP and Juniper's CCNA in addition to my certifications I posses two Bachelor of Science degrees, one in Computer Networks, and the other in Network Security.

One thing I've noticed over my decades long experience is most "beginner" level IT courses are anything but that, some feel like you should take a course first just to understand the current course you're enrolled in. I'd like to change that, I want to start with true beginner's level course, and then build on that foundation. 

I may be a new instructor on Udemy, but I'm anything buy an IT noob.
