Best NDT training I have ever received very professional instruction derek lewellynTrustindex verifies that the original source of the review is Google. Took an AUT class with Thanh and he is very knowledgeable. Went above and beyond showing us just how to run the machine but also went through recommended practices and trouble shooting. It’s nice to learn from someone who has been in the field doing what he is teaching. He even had piping and a mock up vessel with indications to apply the things we were learning. Marco MoreiraTrustindex verifies that the original source of the review is Google. Had a great introduction and training into AUT. Thanh was a great teacher and helped a lot with theory and understanding in field problems. Thanks to a great week JL RTrustindex verifies that the original source of the review is Google. Took a PAUT characterization class to continue my education, for sure game changing in confidence. Especially with an instructor like Thanh that points out precise areas to work on for a better characterization in flaws, and who has over 15Yrs of field experience. Will most definitely believe he will get you on the right track. Mauricio TijerinaTrustindex verifies that the original source of the review is Google. I had an exceptional experience. The instructor is highly knowledgeable, and the hands-on training is top-notch. D MiniTrustindex verifies that the original source of the review is Google. The Ultrasonic Testing class was an outstanding learning experience… It provided a clear understanding of sound wave principles, equipment calibration, and defect detecting methods used in real-world inspection… Mr. Thanh made sure everyone understood the basics before moving to advanced techniques and gave plenty of hands on practice…. It’s definitely a class worth taking if you want to get into NDT or improve your inspection skills….Highly recommended for anyone pursuing a career in nondestructive testing. Sergio NguyenTrustindex verifies that the original source of the review is Google. I recently took an AUT class and UT class with Preeminent NDT, and it was a great experience! The instructor Thanh Nguyen was very knowledgeable, patient, and made sure everyone understood the material. The hands-on training was really helpful and gave me the confidence to apply what I learned in real-world situations. I’d definitely recommend this company to anyone looking to get quality NDT training and expand their skills. Barrinesha PhillipsTrustindex verifies that the original source of the review is Google.
