GBGreat instructor ....Great School I had a very good experience with two courses at CTS. One for A+ and the other for Network + , luckily both with the same instructor Jo Escotal. What I loved about Jo is the way he teaches. He is very passionate and breaks down the material in a way that helps you understand it with ease. He is also very patient and easy going when you asked him questions. The school itself had a very supportive staff and would definitely apply again for more classes.

GBI had the best instructor ever, I passed my CISSP!!! Overall, my experience has been wonderful. I took a CISSP class, and I passed. The material was extremely challenging, however, since it's a Cyber Security course, you should expect nothing less. With a course like Cyber Security, you definitely need a very patient and an instructor who knows his stuff inside and out. Thankfully, my instructor Jo Escotal not only had these qualities but was very helpful anytime I was stuck trying to make sense of anything that was stumping me.

GBAngela did a great job managing both in… Angela did a great job managing both in person and online participants. She was personable and stayed on task. She even explained the appendix in the back of the book and walked us through the process for taking the Excel certification tests. The Naperville location is conveniently located and offers the perfect classroom setting.
