In 1972, Jack Clark founded Clark Gas Company. Our company started with one location and three employees. Since then, we have grown to become one of the larger independent propane companies in the Southeast, serving Alabama, Mississippi, Tennessee, Georgia, Louisiana, and Florida. Whether you are looking for a propane exchange rack for your retail setting or a motor fuel cylinder exchange program, we have the product that’s just right for you. Our new APP conveniently allows you to view invoices and pay your bill.
