Front PicAd-Art is all about signs. That’s what we do; it’s all we do.  Ad-Art has grown from a one-man shop started by Gordon Mariner in the basement of his Georgetown home more than 25 years ago, to a thriving family business. Today we occupy two 5,000-square-foot buildings and employ a team of 11 designers, installers, and production aides. Whatever type of sign you need - vehicle graphics or wrap, dimensional signs, billboards, banners or electrical signs - Ad-Art can deliver a quality product on time and on budget.

Ad-Art’s growth has been aided by the participation of Gordon’s two sons. Matt, who joined the company in 1999, serves as general manager and lead designer. He helps clients choose the best type of sign for their business and walks them through the sign creation process.  Brandon joined a few years later after a successful career in pharmaceutical sales. He sees that signs are properly installed on site – whether that means billboards, community entrance signs, or storefront signage. Both Matt and Brandon are graduates of Clemson University.  Gordon is still a hands on owner, overseeing projects and assisting wherever needed.

The Ad-Art Advantage

Ad-Art has built its reputation on unmatched customer service and signs that are high-impact, durable, and competitively priced. We employ state-of-the-art technology, high-quality materials, and the best production processes.  

Matt, Brandon, and Gordon don’t just work in Sussex County, they are raising their families here. Clients are not only customers, they are also friends and neighbors. When severe weather hits the area, it’s not uncommon for the brothers to travel the region’s roadways, looking for damage.  In business that’s called proactive. At Ad-Art, the Mariners just call it business as usual. 


Thank you so much for the great work you've produced for us this year! You are definitely not the average sign shop!

Your staff goes above and beyond and in a timely manner. This is truly appreciated. We look forward to watching you grow with us!
