Mahr provides aggressive, compassionate representation tailored to each client's unique needs.

As a family-owned and operated practice, this firm is known for providing direct, personalized client care.

He takes the time to listen to your story, answer your questions, and develop a customized strategy designed to secure the maximum compensation or benefits you are legally owed.

Comprehensive Workers' Compensation Advocacy in Iowa and Nebraska

If you have been injured in a workplace accident, your employer's insurance company is legally obligated to provide medical treatment, cover lost wages, and compensate you for any permanent impairment. However, insurance adjusters frequently use various tactics to delay, minimize, or deny valid claims. Attorney Dennis J. Mahr is a highly skilled workers' compensation lawyer who knows how to navigate the complex administrative regulations of both Iowa and Nebraska. He routinely handles serious work injuries, including spinal damage, repetitive strain injuries, construction site fractures, head injuries, and occupational illnesses, ensuring that union members, truck drivers, construction workers, and office employees alike receive their full financial recovery.

Proven Personal Injury and Accident Litigation

A negligent driver or a poorly maintained property can cause devastating physical trauma in an instant. The Law Office of Dennis J. Mahr, LLC, provides robust representation for victims of motor vehicle collisions, including car crashes, commercial semi-truck accidents, and motorcycle accidents. Additionally, the firm represents clients injured in slip and fall incidents, construction accidents, and premises liability claims. Attorney Mahr handles all communications with the negligent party's insurance company, conducts detailed scene investigations, collects crucial medical evidence, and builds a powerful case to secure compensation for your pain, suffering, medical bills, and lost earnings.

Navigating Complex Social Security Disability Claims

Filing for Social Security disability benefits can be an exhausting and complex administrative process. The vast majority of initial claims are rejected, leaving disabled applicants discouraged and without income. Dennis J. Mahr brings a practical, comprehensive understanding of the Social Security Administration's guidelines to help you successfully secure Social Security Disability Insurance (SSDI) benefits. He assists in organizing extensive medical documentation, preparing you for administrative hearings, and presenting a compelling case before administrative law judges. If you have been denied, he offers the targeted appeal representation needed to overturn the decision.
