Male Minimum Security - Opened 1961

Howard McLeod Correctional Center (HMCC) is a minimum-security male prison 30 miles southeast of Atoka. Most of its nearly 700 inmates produce cattle, hay, pecans and firewood for ODOC Agri-Services on the facility's 5,300 acres.

Mack Alford Correctional Center (then Stringtown Correctional Center) inmates built the facility in 1962. HMCC's namesake, Howard C. McLeod, was a former Oklahoma State Penitentiary warden whose passion for providing inmates meaningful work was widely known throughout the agency.

Fourteen dinosaur skeletons have been found on HMCC's grounds.


Many inmates lack education, a key component in avoiding re-incarceration. HMCC offers literacy courses as well as Pre-High School Equivalency and High School Equivalency diplomas.

College courses, which are not provided with state funding, are available to inmates who can afford them, or those who have alternative funding or scholarships.

Criminal Thinking

HMCC offers Thinking for a Change, Partners in Parenting, and Victims Impact programs to address the thinking, judgment errors, and negative relationships linked with criminal thinking/behavior.


HMCC inmates can get technical training through a CareerTech Skills Center, which trains them for workforce entry after release. CareerTech also helps inmates find skill-related employment after release.

Courses include Precision Machining, Transportation Distribution & Logistics for Warehouses, and Welding.

Visitation Regulations

Visitation hours vary by each facility. An inmate's security level dictates how many hours he or she may visit with approved visitors.

HMCC is a minimum-security facility, and its inmates may receive up to eight hours per week, excluding holidays.

State-recognized holidays that fall on Monday through Friday are "free" visiting days. That means that, while an inmates' allowable number of hours for visiting still corresponds with their security level, holiday visitation will not count toward their total number of allowed visitation hours.

If the holiday falls on a Saturday or Sunday, visitation hours count on total visiting privilege level hours.

Level I
One hour per week -
Inmates are permitted a one hour non contact visit per week from 6-7 p.m. Saturday, except for during state holidays. If the holiday is on any day than Saturday, the inmate can visit on that day, as well as Saturday, from 6-7 p.m. Visitors must check in by 5:45 p.m.

Level  2
Three hours per week -
Visiting  hours  will  be at 12-3 p.m. either Saturday or Sunday plus state holidays.  

Level  3
Five hours per week -
Visiting hours will be 10 a.m.-3 p.m. either Saturday or Sunday plus state holidays.

Level 4 
6.5 hours per week -
Visiting hours will be 8:30 a.m.-3 p.m., either Saturday or Sunday plus state holidays.   

Special Visits

Special extended visits are allowed for staff-identified individuals who travel long distances, volunteers or team members who partner with ODOC in reentry services, attorney/clergy, etc. The facility's warden determines the length and conditions of all special visits. Special visits for ministers/religious leaders must be scheduled in advance through the Warden. 

Requests for special visits must be made by the inmate using the appropriate request form and must be submitted by the inmate to unit staff at least two weeks in advance so verification can be made. Exceptions to time frames may be considered in emergencies.

If the special visit is allowed on the inmate’s regular visiting day, the length of the visit will be determined by the inmate’s visiting privilege level criteria. If the special visit is during the work week, the length of the visit will be determined individually and not to exceed two hours. However, if the inmate is Level 1, special visits must adhere to non-contact policy.

Inmates can receive mail at any time. Include their name, DOC number and housing assignment if known in the address.
