Prison Background

Federal Administrative Maximum Florence (ADMAX) is an administrative-security federal prison in Florence, Colorado, which houses male inmates. The facility opened in 1994. It is part of the Florence Federal Correctional Complex.

The supermax prison in Colorado, also known as ADX Florence prison and “The Alcatraz of the Rockies,” is the nation’s only level 6 supermax security prison. It houses the most dangerous offenders in the federal prison system.

Mother Jones describes the prison as “pretty close to hell.” Prison administrators banned both of President Barack Obama’s books at one point. Prison officials called the books “potentially detrimental to national security.”

Media reports indicate that a member of the Bureau’s elite Special Operations Response Team (SORT) was convicted of stealing and selling flash-bang grenades on the black market. At least one inmate has committed suicide, fellow prisoners have murdered three inmates, and numerous inmates have mutilated themselves at the facility. Multiple class-action lawsuits have also been filed, alleging a lack of medical and psychological treatment.

The ten housing units range in formats and types. They include a control unit, special housing unit, high security, general population, and pre-transfer unit. The general experience of ADX Florence prison inmates is that of solitary confinement.

Health Services

Sick call, dental sick call, physical examinations, medications, eyeglasses, chronic care, preventive health services, emergency services, diagnosis and treatment of chronic conditions, and mental health care are provided to inmates. Mandatory HIV testing is performed when there are risk factors, and the test is clinically indicated, or surveillance testing is required.

Inmates are screened for MRSA and TB annually. Paper sick call requests must be filed for evaluation of healthcare needs. Health Services staff perform these clinical evaluations primarily through video cameras in inmate cells.

Psychology Services

Psychology Services representatives interview inmates within 14 days of arrival at ADX Florence. Psychology Services offers a variety of programs through the in-cell closed-circuit TV, in coordination with the inmate’s Unit Team, in place of group counseling. These programs include Stress Management, Anger Management, and various other topics.

These classes are sometimes completed using paper packets that inmates fill out and return. If an inmate successfully completes a formal program, he will receive a certificate. For psychiatric care, inmates have the services of a psychiatrist at MCFP Springfield via teleconferencing equipment. Tele-psychiatry clinics are held twice a month.

Residential Drug Abuse Program (RDAP)

ADX Florence does not house a Residential Drug Abuse Program (RDAP). A Drug Education Program, the Non-Residential Drug Abuse Program (NR-DAP), and other drug abuse programming are available.
