Class instructor is very knowledgeable of the IRC code and use various code books to find the reference that supports the code. He took time to answer and explain any questions the students may have had. over all the class was very informative with a lot of detail on how to navigate the code materiel. Michael J.

The class exceeded my expectations. We covered a lot of material in a short period of time, but the recordings and additional course work for 45 days should enhance my ability to pass the course. Well laid out Victor C.

I'd never attended this type of training before, and I honestly thought it would be a bit boring, but Mr. Julio delivered the course in a fun and engaging way. He made the time spent in training enjoyable. I learned and had a good time. If I had to take another training program in the future, I'd choose Mr. Julio. Vicente M.
