The Denver Sheriff Department was created on December 2, 1902 with the creation of the City and County of Denver.  In 110 years the Denver Sheriff Department has seen changes in facilities, locations, inmate populations, personnel, etc.  However, the one thing that has remained constant in 110 years is the commitment and dedication of Denver Sheriff Department personnel.
Since 1902, the Denver Sheriff Department has moved from facilities made up of a few hundred square feet to the hundreds of thousands of square feet that make up both the Van Cise-Simonet Detention Center and the Denver County Jail.  We have gone from handwritten forms and typing on typewriters to a virtually paperless state-of-the-art Jail Management System.  In 1902 the Department began with a handful of employees and has grown to over 890 dedicated men and women, both uniformed and civilian. 


Our agency is currently accredited by theAmerican Correctional Association (ACA)and the National Commission on Correctional Health Care (NCCHC). We are a proud agency that is committed to employing the best practices for the community that we serve while being fiscally responsible.

The  Triple Crown Award

was established by the National Sheriff’s Association to recognize those sheriff’s offices which achieve simultaneous accreditation from the Commission on Accreditation for Law Enforcement Agencies, the American Correctional Association, and the National Commission on Correctional HealthCare.  Achieving these accreditations individually is a daunting task.  Acquiring all three at the same time is an extraordinary feat.  In fact, the Triple Crown distinction is so rare, that since the establishment of the award in 1993, fewer than 35 sheriffs' offices have qualified.

The  American Correctional Association is the oldest and most prestigious correctional membership organization in the United States. Founded in 1870, ACA currently represents more than 20,000 correctional practitioners in the United States and Canada.  At its first organizational meeting held in Cincinnati, Ohio, in 1870, the Association elected then-Ohio governor and future U.S. President Rutherford B. Hayes as its first president.

During the 1960s and early 1970’s, United States law enforcement faced a number of large-scale civil disturbances.  Many American cities experienced riots with significant loss of life and property damage.  Many citizens lost confidence in the law enforcement agencies due to their seeming inability to prepare for and deal with these events. 

Law enforcement agencies were viewed as unable or unwilling to learn from others’ mistakes and as having little, if any, coordination between themselves and other agencies.  Law enforcement officers were often viewed as under-trained, and their selection and hiring practices often were discriminatory.  Policies and procedures were often poorly written or sometimes, nonexistent, and many in the general public did not respect law enforcement officers as professionals.  Issues of accountability, integrity, liability, performance, and community partnership dominated the public dialogue and media coverage of law enforcement. 

In response, the United States Department of Justice provided a grant to the four leading law enforcement executive associations to advance law enforcement professionalism by establishing voluntary standards.  The organizations were: International Association of Chiefs of Police (IACP); National Organization of Black Law Enforcement Executives (NOBLE); National Sheriff’s Association (NSA); and Police Executive Research Forum (PERF).  The result of this initiative was the creation in 1979 of a private, non-profit corporation: “Commission on Accreditation for Law Enforcement Agencies, Inc (CALEA Process and Programs Guide, pg 1-1 and 1-2).

The  National Commission on Correctional Heath Care is dedicated to improving health services in jails, prisons, and juvenile confinement facilities.  Incorporated in 1983, its roots are in the early 1970’s as a project of the American Medical Association.
