What Our Students Say
“I have like “REALLY” enjoyed this class. I have enjoyed taking the engine apart putting back together and trying to start the engine (even though it would not run). I have also enjoyed learning what tools are called (that you use to take things apart such as a engine). I have enjoyed working with the teacher who has answered every question we ask, to the best of his ability. If he ever does do a “MECHANICS ADVANCED” class, or whatever it is called, if there is room I would love to do it.”
“As a former student of Mr. Barnes at the college level, I can say without a doubt what an excellent teacher and mentor he is. His class preparation was always spot on and he was able to answer any questions to everyone's satisfaction. He always made classes interesting and fun.”
“Thank you Mr. Barnes. For everything you have done for me. As my teacher you taught me more then just how to fix vehicles. You taught me that a man who loves and walks with Christ wins. We didn't talk to much about God but we didn't have to. By your actions and by your words it was very apparent you had something I wanted. So thank you for guiding me to be the man I've longed to be with my walk with Christ and with my knowledge for the job I was born to do. You will always be more then just a school teacher in my eyes.”
