Great class and very informative. Santiago always has a positive attitude and answers all questions and makes sure you understand everything he is teaching. Santiago doesn’t pretend to know it all even though he is very knowledgeable in all aspects of DOT and safety and he will show you how to find the answers your looking for in the books so you understand the actual laws. The classroom materials are detailed and help you follow along with his instruction. I highly recommend any course he has to offer; this was the best safety training I have ever attended. Looking forward to his next training in Laredo.
