    Our Story

    Three Generations of Sign Makers

    Family owned since 1985. How the Martin family built a Marietta sign company on craftsmanship, quality materials, and personal service.

    1985

    Built One Generation at a Time

    Every business wants to make a lasting impression. For Rudy Martin, that meant quality signage. During his early days in real estate, he saw how poor-quality signs undermined a company's image, and he got frustrated enough to do something about it.

    In 1985, Rudy and his wife Vivian started One Hour Signs, Inc., now doing business as 3GM Signs and Graphics. From day one, their philosophy was:

    It should be simple to get quality signs that help your business look its best.

    Their son Damon Martin joined in 1987. In 2002, Damon's wife Dee came into the business as well. Together they carried the same standards and family commitment forward.

    In 2013, Damon's son Michael joined the company. Today he serves as Vice President and General Manager.

    We're three generations strong, and that spirit lives on in 3GM Signs today. The name stands for Three Generations of Martins.
