At the Tiefenthaler Law Office, our practice is primarily limited to the following cases: personal injury, workers' compensation, and criminal defense.  We practice in all stated and federal courts in Iowa, Nebraska, and South Dakota.

Personal Injury

Accidents happen every day, but when you suffer an injury due to someone else's neglect, you deserve compensation for your pain and suffering.

If you've experienced any of the following, give us a call:

  • Automobile accidents
  • Catastrophic injury
  • Medical malpractice
  • Motorcycle collisions
  • Truck accidents
  • Wrongful death

Our personal injury lawyer in Sioux City, IA will gather facts about your case so you can receive complete restitution for your injury

Workers' Compensation

You have the right to work in a safe environment.  The law demands your employer comply with safety standards. If you received an injury on the job because your employer failed to meet these regulations, workers' compensation will help you cover your medical bills.

However, many adults struggle to file workers' compensation claims. As a result, they don't receive full compensation because they miss the filing deadline or because they skip an important step when they file. 

When you come to Tiefenthaler Law Office, our workers' compensation lawyer in Sioux City, IA will guide you through the claims process and answer any questions you may have. 

Criminal Defense

If you've been arrested or charged with a crime, don't wait to meet with our legal team. We'll do everything we can present your case in a favorable light. With our team at your side, you may even receive a lesser sentence on the following: 

  • Drug Charges
  • Assault 
  • Sex Offenses
  • Theft 

We can also arrange for your appeal.
