Mack Alford Correctional Center

Mack Alford Correctional Center (MACC) is a multi-functional, state operated, correctional facility that houses more than 500 male inmates in a medium-security, long-term unit. MACC also has a minimum-security unit with approximately 260 male inmates.

Located in Stringtown, Oklahoma, Mack Alford Correctional Center (MACC) was established in the 1930s as a sub-prison of Oklahoma State Penitentiary in nearby McAlester. It helped the state separate first-time convicts from OSP inmates, and also provided work opportunities on the farm.

After that, the facility had stints as a sexually transmitted disease hospital, a German prisoner of war camp, and a school known as the Stringtown Boys School.

In 1956, it returned to being a farm. New fencing and towers were later added as it became a medium-security prison (named Stringtown Correctional Center in 1977). Its name was changed to that of a former warden in 1986. Today, MACC is home to more than 800 inmates.

Oklahoma Correctional Industry (OCI) factories, located on facility grounds, teach inmates to renovate furniture, produce metal signs, and sew garments. Inmates working for MACC AgriServices division help run a 150 herd cow/calf operation.
