Welcome to Great Lakes Granite & Marble Stone University(Online Education)

This site was designed with one purpose in mind, educating our associates, partners and customers.

In it you will find seven sections that will give you detailed information of the most important elements in the Residential Natural Stone Industry.

Each one of these sections is an integral part of the next. After the completion of each section, you will be able to test your knowledge by submitting your answers to a 6 question quiz.

If you choose to complete all of the tests, and pass them, you will receive a “Natural Stone Certification”.

Our true goal, more than providing you with the recognition mentioned above, is to ensure that as a company we provide you with the most accurate information to ensure that the end costumer is completely satisfied with their product and experience with us.

When you complete this online education effort, you will have acquired a good set of tools that will allow you to do just that.
