How do you teach the driest topic in industry? With humour, patience, a little Devil’s Advocacy and some intentional misdirection. That’s how I help you rise from GD&T newbie to an effective user (Oh, and of course the best training material in the industry helps!). GD&T isn’t a sexy or exciting topic, and it’s not trivial to understand. I still remember what it was like in those early stages of learning… boundaries, symbols, datums,…whoa. They say you need to see something at least three times to learn it, but repetition is boring. When the presentation fronts the same material in different ways again and again, you start to learn it effectively before you realize it. I know I’ve done my job well when a training client tells me they felt like they were just having a good conversation and understood the material before they realized they had learned it.

I’m a Professional Engineer with over 20 years of hands-on experience in engineering and manufacturing. I’ve been involved in production, field service, product development and design, project management and process development/improvement/implementation. Managing a global GD&T implementation for design, manufacturing, quality and suppliers on three international business campuses taught me a lot about change management, and I’ve presented to groups about the pitfalls relevant to any technology implementation, and on the value of GD&T.

Since receiving a Bachelor’s Degree in Mechanical Engineering with a Concentration in Management Studies, I’ve participated in a number of industries:

  • Aerospace
  • Armoured vehicles
  • Automotive
  • Medical devices
  • Agriculture
  • Composites
  • Injection molding
  • Packaging
  • Consumer goods
  • Electronics / automation … and others

While working and teaching, I’ve spanned a good chunk of the globe; England, France, Germany, Luxembourg, Czech Republic, Indonesia and Tunisia, some 23 states in the USA, Mexico, and of course across Canada. While I’m a GD&T trainer, I’m also a learner at every session. I enjoy a good challenge, a new application, an opportunity to help someone get a deeper understanding of their designs and processes, and find a better way to communicate their design intent.

  • "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".

  • "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."

  • "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."
