Sioux County Sheriff

Sheriff Altena announces several staff changes

Sheriff Dan Altena announced several changes that will take place at the Sioux County Sheriff’s Office.

Jail Commander, Judy Plendl, will retire effective December 31, 2019.

Plendl has been an employee with the sheriff’s office since 1987. She has served in a variety of roles. In 2005, newly elected Sheriff Altena appointed Plendl to the position of Jail Commander.

In 2018 the Sioux County Jail won the “Best of the Best” jail award for medium sized jails in Iowa. This was the first time Iowa had presented such an award. Plendl’s leadership was very instrumental in the Jail receiving this accolade. It was based on administration, documentation and cleanliness.


Jailer Davis De Jong has been promoted to the position of Jail Commander. De Jong has been employed by the sheriff’s office as a jailer since January of 2009.









Deputy Justin De Bruin has been promoted to the rank of Sergeant.

Deputy De Bruin has been employed at the sheriff’s office since October of 2005. He has been one of the canine officers at the sheriff’s office since 2006. DeBruin has received top awards at several National and Regional competitions, including the United States Police Canine Association.
