Mark was born in Dallas, Texas to Henry Lee “Hank” Granberry and Mena Gene Wilbourn. He has two brothers Michael Granberry (Nancy Churnin), Larry Granberry (Jill Granberry), and a sister Mallary Henrichs (John Henrichs).

As a young man, Mark worked at Texas Screen Process Supply, where his father was President. The company was an division of Texas Sign Supply, which was founded in 1946 by John Lamb and Roy Baxley. Lamb was also founder of Cinncinati Sign Supplies of Cinncinati, Ohio, and Roy Baxley. Mark’s father had gone to work for Texas Sign Supply company as a warehouse clerk in 1950, and slowly worked his way up in the company.

The Texas market quickly expanded and Texas Sign Supply moved into larger headquarters on North Walton Street in the Deep Ellum section of Dallas where they continued to grow. In 1962, the company also expanded northwards with the founding of Neo Sign Supply in Oklahoma City to better serve their customers in Oklahoma, Arkansas, Kansas, and Missouri.

The screenprinting market was advancing rapidly and in 1966, they purchased another building across the street at 310 North Walton Street and opened Texas Screen Process Supply Company, Hank Granberry was promoted to President of Texas Screen Process Supply and Baxley as Vice-President of Texas Screen Process Supply, and  President of Neo Sign Supply. Eventually, the two companies would expand the 310 North Walton Street location in Dallas and combine the two companies in the same building. Roy served as Chairman of the Board for all three sister-companies. Eventually, Roy Baxley and Hank Granberry would purchase the company from John Lamb.

In 2001, the three companies were merged into a single company with Mark Granberry, taking the reins of the company. Mark merged all three companies – Texas Sign Supply, Texas Screen Process Supply, and Neo Sign & Screen Supply — into a single company – Graphic Solutions Group with Roy continuing as Chairman of the Board. Hank Granberry passed away from pancreatic cancer on Aug 11, 2001.

In 2006, Mark Granberry purchased the company from Roy Baxley and became sole owner of the Graphic Solutions Group, which evenually became GSG.

Today, GSG is a leading national supplier to the sign, digital imaging, and screen printing industries. The company has moved to larger headquarters at 4601 Spring Valley Rd., Dallas, Texas.
