I have been going to Jon Dennis since June of 2013 and he is the best welding instructor I have ever met! I have made lots of projects there with him and have even gone and helped him on some job sites. My teacher in school (2013) recommended him to me and I'm glad I started going to him! He has certified me in some areas of welding and I'm still working on other certifications, but he will work one on one with you if you need extra help. He has always been very helpful, nice, and has encouraged me that I can do things I didn't think I could do. I highly recommend Dennis Welding School to anyone

Jon Dennis is the best welding school teacher. I feel this man has forgotten more about welding that most guys know about welding. He is a private welding school so he will teach you real world tricks of the trade. Not a state tech school that will only teach you how to pass a welding test. He was recommend to me by an professional welder to take his class. I am glad I did.
