I trained under Mr George and he was amazing! He took the time to make sure we understood everything he was teaching and even would drop a few jewels that will help us out in the field. A very wise man with a lot of experience under his belt who isn’t stingy with sharing the knowledge.

Trust me. If you want to go to trade school for electrical, plumbing or HVAC in this area, YOU want to go to NTI. The teachers and staff are just top-notch people. I called them 6 months after I graduated for help and Ralph got back to me right away to help me find a resolution.

Newly Graduated! Easy to learn process! I took the plumbing course with Lary Kranz and it was a phenomenal experience. I cannot wait to enter into the work force with the training I received from him, and this amazing school.
