�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.� ~ Bryan Jones
�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 anyone who needs his services for whatever purposes.� ~ Ivo Ngala
�Brother I have known you for years now.... we may never have worked together but I respect what you do , bringing up the next batch of individuals.... passing along what we know... is something worth my attention and admiration.... Keep on keeping on... Cheers Brother.� ~ Joseph Duran

Why DTM Enterprises?

DTM Enterprises provides quality classroom training, and consulting services.  We know how to help students succeed! I recently got off the phone with an individual wanting to take another class for the CWI prep as they have taken the test twice and can't quite make the cut. They had taken one of the competitor's two week crash courses, but had not retained enough to pass. Something we don't really advertise as much as we should is our consulting services. Nine times out of ten, I can look at someone's test results and know where they need shoring up. At $100/hour we can hone in on where they need shoring up, without wasting their time nor mine. Why take and pay for an entire class when you can invest two, or three hours and get what you need? I can not count the ones who opt for the consultations and inside of fifteen minutes exclaim, "man, if I had know this I would have passed already." Knowing the competencies of our competitor's, I know the material was covered; they just had not grasped the concept.

We know how to help students succeed!
