When I started studying for my API 653 Certification, everything seemed too complex and difficult for me until my first class with DTM Services. Apart from breaking down complex engineering concepts into simple comprehensible facts, David was so meticulous and knowledgeable in giving me the right approach to my studies. From then on, I was set for success and it finally came. I would recommend David and his enterprise to any one who needs his services for for whatever purposes.

Recently took my second class with David. He was very instrumental in my success the first go round. Very knowledgable, very helpful and id easily recommend him in the future.

Dave McGrath is a very experienced inspector with many years in the industry. As an inspection professional Dave has made himself available to me on multiple occasions. Truly and SME for inspection and CWI. Would highly recommend him as a trainer and as a person.

If you are looking to get API 510, 570, 653 or AWS - CWI certified, look no further. David with DTM Enterprises is a retired LyondellBasell inspection supervisor with years and years of hands on inspection experience that not only knows the books but knows why it s in there.
Others may know the test that constantly changes... David not only knows the test but can teach from experience. Best API and AWS test prep class out there.

Small class sizes with great one on one instruction. Took the CWI prep class and passed 1st attempt. Instruction goes above and beyond. Read the material and come to these classes prepared and you will pass!

Will be back for the API classes.

Thanks DTM.
