Consulting and Mentoring

We can help you improve the GD&T on your company drawings. Our experts can hold stand-alone mentoring sessions or use your drawings as examples in the live courses.

Why Choose GeoTol?

Our training programs feature practical applications of GD&T. We have been refining our training programs and approach for over 40 years to cover what you need to know to work with GD&T in an engineering, manufacturing, or quality environment.

The course authors Al Neumann and Scott Neumann have served on the ASME Y14.5 and other subcommittees to help write ASME standards for over 40 years.
The American Society of Mechanical Engineers (ASME) uses our training programs and instructors to deliver their public and onsite GD&T courses.
Our training is used by many top companies in the fields of automotive, industrial, aerospace, medical, consumer products, and defense.
Our training programs integrate animated computer graphics, wood and plastic models, and exercises with polling technology to create an engaging learning experience.
Our onsite/virtual training can be supplemented with our online self-paced course for retraining and new hires.
The GD&T training approaches the subject from the design, manufacturing, and quality points of view to allow attendees to communicate better with their team afterwards.
