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.
