Charles' father, Charles P Howard, would work as a truck driver for portable toilet company and started CALLAHEAD in 1976 at a location that used to be a gas station in Broad Channel, NY. In the early 1980s, the business only had about 150 potties and one employee with one truck. In 1981, CALLAHEAD was turned over to Charles W Howard. Today, Charles has built the company up to 12,000 portable toilets, 150 employees, and 75 trucks.
