Will Develop a Strong Foundation in Great Practical Detail After reading countless materials on GD&T, I finally stumbled upon Mark's course and am grateful for that as I have now truly learned a strong foundation in GD&T. Mark makes it intersting, explains the benefits of GD&T so one can see the value of learning and implementing it, and creates a roadmap of the Big Picture of GD&T so one can have a feel for what it is first. Then he fills in the details in the right order presenting the concepts and building on previous concepts in the right order so that this information is converted into long-term memory. If you take this course, you will leave the course feeling like it is a great value for your dollar and for your career progression. He definitely overdelivers thus exceeding customer satisfaction and I would recommend this training over all others with a passion as I know first hand the benefits of taking this course. - Shawn Guillory
