Dr. Christensen has worked within the correctional field for the past 41 years. He has researched extensively the premise of evidence-based or outcome-driven practice within a correctional milieu and initiated several innovative correctional programs, including the Dutchess County Jail Transition Program (DCJTP), which has been recognized nationally for significant recidivism reduction and the enhancement of general public safety. In addition to his responsibilities as jail administrator, Dr. Christensen also served in an advisory capacity to the Executive and Legislative branches of County Government as chair of the Dutchess County Criminal Justice Council (CJC) and authored legislation to counter the effects of police racial profiling and coordinated criminal justice system master planning and the implementation of system-wide, evidence-based criminal justice practice. For his many contributions to the field of corrections, Dr. Christensen has received recognition from numerous local and state entities and, in 2007, received national acclaim by being named the Jail Administrator of the Year by the American Jail Association.
Since his retirement from public service, as president of Justice Solutions, Inc. and Corrections Partners, Inc., Dr. Christensen continues to work with leaders throughout the field of criminal justice to enhance the implementation of evidence-based practice throughout their systems of criminal justice. He has developed the Applied Correctional Transition Strategy (ACTS), a comprehensive software suite designed to enhance all aspects of daily jail transition as well as provide policy-makers with essential information to ensure that allocated resources lead to the most productive and cost efficient outcomes. Dr. Christensen continues to serve on several national advisory boards investigating innovative responses to pressing issues within corrections and author publications for the field at large, inclusive of the Transition from Jail to the Community Implementation Initiative/Toolkit, Evidence-Based Decision Making Initiative, and the Prison Rape Elimination Act National Review Panel.
