  • "I've learned more in just a few hours with the Tec-Ease GD&T Hierarchy Coach than in 12 weeks taking a similar on-line program. I look forward to the time I get to spend viewing the presentations and taking the interactive quizzes. Here at FOX the Tec-Ease GD&T Hierarchy Coach is rated "best in class".

  • "Thank you for all that you do. Your "Tips" are INVALUABLE -- I frequently refer to the archive for advice when I run across a sticky tolerancing puzzle."
    - Barbara P.
  • "I must say that I think you are the best GDT trainer/vendor of the many available. I have purchased your GDT charts, aids, and "The GDT Hierarchy" and found them to be clear and well illustrated."

  • "I absolutely love this course! (The GD&T Hierarchy Coach) I can go as slow as I want and go back and review slides if I need to. This is the way to go. I don't interrupt others learning, yet I get to fully understand before I move on."
    - Gwen M.
  • "Things are going well with our project. In less than a year we will be shipping a clinically significant, quality changing product to China from a US manufacturer. Cost competitive with great clinical outcome. I love the approach. I appreciate your help on this project. We have had a lot of feedback from our supply base saying great use of datum's and design for manufacturability."
