Grace Outdoor Advertising
SCBiz Staff // May 18, 2026//
Grace Outdoor is a locally owned family business based in Columbia, operating both traditional and digital billboards in Columbia, Greenville, Florence, Fort Mill, Spartanburg and Charleston.
Diana W. Stevenson is CEO of the company, which has been in business for 25 years.
“I am most proud of our team and the culture we have built here at Grace. We value our members and seek to make our work-place one of inclusion, cooperation and collaboration.”
Stevenson was named to the board of the Outdoor Advertising Association of America last year. She also serves as the Independent Council Chair-Person for the OAAA.
Grace Outdoor Advertising has been in growth mode in recent years and hopes to continue that in the coming year.
“A big part of our growth story is inventory. We’re building between 8 and 10 new billboard structures each year and adding another 5-10 through acquisition,” the company said. “Every location we develop, we keep and operate because we’re here for the long haul, not a quick return. We’re proud to be a permanent part of the communities we serve. We are not interested in selling our inventory to make a quick buck.”
