Trey McMillan leads Lowcountry Oyster Company as owner and president, guiding the 13-employee oyster farm through a five-year, $6.4 million expansion in its second year.
A Wando High School graduate who chose hands-on experience over college, McMillan built his career fishing tournaments worldwide before establishing his oyster operation. The company recently completed its state-of-the-art 15,000-square-foot processing facility, the Oyster Outpost, capable of packing 14,000 oysters per hour with 5,000 square feet of refrigerated space.
“Surround yourself with people you aspire to be,” he says, advice guiding his leadership approach.
McMillan serves as president of the South Carolina Shellfish Growers Association, South Carolina state representative for the East Coast Shellfish Growers Association, founding board member of the Coalition for Sustainable Aquaculture, and board member of Charleston Restaurant Foundation.
His first job as a bait cutter and boat cleaner on a Shem Creek head boat taught him that local waterways are a grocery store requiring knowledge to navigate.
McMillan identifies seed supply of native genetic oysters and cold freight logistics as the industry’s biggest challenges, defining success as relentlessly pursuing a clear vision.
