Sioux City Attorney


Nick E. Wingert is an Attorney and Partner at Hall & Wingert, PLC. He is licensed to practice in Iowa. He is also a life-long resident of Sioux City. He is a graduate of the University of South Dakota, School of Law, and Morningside College where he earned his undergraduate degree.

Nick helps individuals fight for custody of their children, understand child support obligations, or their rights during a divorce. If law enforcement stopped you for a traffic violation, which resulted in an arrest for operating while intoxicated or possession, Nick will assist you in determining whether law enforcement violated your constitutional rights. He has successfully challenged evidence gathered after traffic stops on constitutional grounds which have ultimately resulted in case dismissals.

You may find yourself in a position where you disagree with the outcome of your case and whether any options exist to challenge a decision made at the district court level. Not all attorneys practice appellate work. Nick will analyze your case and help you determine whether appealing to the Iowa Supreme Court or Iowa Court of Appeals might be in your best interest.

“I have known since I was in high school that I wanted to become an attorney. There is no better way to serve clients than to give them a voice in the system that they would otherwise not have—serving their best interests with passion.” These are the values that he takes to the office every day. Nick is very dedicated to his clients, fostering a professional relationship on a very personal level.

He focuses on obtaining the client’s desired result. “It is important for me to work obsessively on my cases. I want my clients to know that I put my heart and soul into winning his or her case.”

When Nick is not working hard for his clients, he spends his time with his two children and volunteers in the community when he has time. Nick likes to stay active by running and cycling and loves college football season. While he is an avid Iowa Hawkeyes fan, he has represented all football fans including Nebraska and Iowa State football fans and always strives to obtain the result for the client no matter your football team.

Nick has attended training developed by the National Highway Traffic Safety Administrations (NHTSA) regarding Standardized Field Sobriety Testing (SFST). This training, used to train police officers in the detection of impaired drivers, teaches students to understand the tasks and decisions involved in identifying the intoxicated driver, OWI detection process, and the effects of OWI enforcement. It covers the three standardized field sobriety tests: 1) Horizontal Gaze Nystagmus; 2) Walk and Turn; and 3) One Leg Stand.

Further, the class instruction teaches students how to administer the three NHTSA standardized field sobriety tests, the typical clues of intoxication by alcohol, divided attention testing, and scoring protocols SFST validation studies. This education allows Nick to analyze and identify potential testing errors by police officers regarding the administration of the field sobriety tests. Nick has also attended training regarding the BAC Data Master, otherwise known as the DMT breath testing device used in OWI/DUI investigations.
