TESTIMONIALS FROM STUDENTS

“Instructor kept class involved. Teaching style was great.” - April H.

“I highly recommend all my RT inspectors to attend QTS RAD Safety. Ken put on one of the best 40 hour classroom training I have attended over the past 12 years!” - Nick P.

“Ken was an amazing teacher really kept it “exciting”. I can’t recommend him enough.” - Chris

“Another great class. I plan to come back on my own to take my practical and Phased Array. Thank you!” - Chris H.

“The instructor was willing to stay after class to help with individual questions. This is very helpful because everyone has different equipment and work types.” - Jason S.

“Overall I feel as if I learned a lot this week. I feel much more confident scanning with the background knowledge. I would highly recommend Max as a great teacher for this course.” - Emily L.

“The support from Justin and Ken has been fantastic. I have also worked with Matt, MT inspector, and he is very prompt, courteous, very professional and good to work with. I appreciate the help.” - Roger B.

“The real world inspection methods were a great idea. It was bit of a hiccup when Max had to leave for a meeting on day 2. All in all he did a great job covering everything and answering all questions we had. Subject matter was on point and had a nice flow daily. Advice hold on to this trainer and maybe give him a raise!” - Jason A.

‘Max is a very good instructor. He seems to know the material well and did a very good job explaining the different indications and terminology.’ - Joe B.
