25-cake

In 1985, Alex Krulikowski began a small start up company that provided training and consulting in a little-known discipline called geometric dimensioning and tolerancing. Twenty-five years later, Effective Training Inc. has evolved into a corporation that provides GD&T training, products and services to organizations across the globe.

Alex and ETI would like to thank our clients for supporting us for the past 25 years. We look forward to providing you with GD&T products and services in the future. Please take advantage of our gift to you: 25% off selected products and services.
