Mobley Gin Company of Doerun, Georgia was established in 1985. John M. Mobley and sons, Mark, Mike, and Patrick, purchased the former Toney Brothers Gin located on Highway 133 South. In 1986 the Mobleys refurbished the Toney Brothers Gin with more modern machinery from North Carolina. In 1990 more machinery was added to upgrade and increase ginning capacity. In 1995 the Mobleys purchased property on Highway 270 and built a modern gin plant that was capable of processing 50 bales and hour with a capacity of 75-80,000+ bales per year.

With ownership of the gin, businesses were added to support the operation. Mobley Warehouse Company was created to store cotton processed at the gin. Doerun Transport Company came into being to provide vehicles for transporting the cotton from the fields to the gin and then to the warehouses for storage.

In July 2009, John Mark Mobley joined his father in the cotton ginning business. The goal of Mobley Gin Company has been and will continue to be to provide the cotton farmer with the best customer service possible while striving to meet all of their ginning, warehousing, and marketing needs.
