To serve & Protect
With sadness we have watched the outrage and fear building in our nation.
As a law enforcement agency, called to serve the public, we have done our best to build trust with the people we serve.
We continue to be committed to our Vision Statement:
The Sioux County Sheriff’s Office will be dedicated to preserving a high quality of life and the enhancement of public safety. We will be committed to serve with professionalism, diligence, respect, integrity and concern for all people. We will foster an environment in which the sheriff’s office and the community work together as catalysts for positive community development.
Our men and women enter this profession with a sincere desire to preserve and respect the sanctity of life.
We pledge that we will continue to offer our hand to build community partnerships and maintain an environment of openness and respect for all whom we serve.
