Our Primary Practice Areas

We represent clients in connection with the following:

  • Commercial Disputes. We represent clients in a variety of commercial disputes, including business torts, contract disputes, employment disputes, and industry-wide litigation. Our clients include building owners, retailers, construction companies, and manufacturers ranging in size from Fortune 500 companies to locally-owned businesses.
  • Construction Disputes. We aggressively defend construction companies, contractors, architects, and engineers in construction disputes throughout the country.
  • Employment Matters. We regularly defend employers who are facing claims of defamation, breach of employment contract, retaliatory discharge, trade secret claims, wrongful termination, and violation of civil rights laws and labor statutes.
  • Fire and Explosion. Our focused legal team combines its understanding of chemistry and other scientific principles with applicable legal standards and procedures to effectively defend fire and explosion claims.
  • Industry-Wide Litigation. Our lawyers are consistently asked to serve as national, local, and lead counsel for several Fortune 500 companies and other well-recognized entities in connection with industry-wide litigation and mass tort claims.
  • Insurance Coverage Disputes. Insurance coverage is an integral part of any successful business and we are regularly called on by major insurance carriers throughout the country to assist them with insurance coverage disputes.
  • Personal Injury Defense. We defend property owners, employers, and businesses in connection with various personal injury claims, including slip and falls, auto accidents, inadequate security, and defective products.
  • Product Liability Defense. We defend manufacturers, retailers, and distributors in connection with personal injury and property damage claims that result from alleged design or manufacturing defects.
  • Professional Liability. We often represent architects, engineers, designers, and other professionals – along with their insurance carriers – in connection with tort claims and other professional liability claims.
  • Subrogation Issues. Workers’ compensation and insurance claims often involve complicated issues related to subrogation, which can have a significant impact on a business. As such, we routinely advise clients with respect to the following subrogation areas: commercial property, residential property, auto insurance, and workers’ compensation.
  • Medical Malpractice. As part of our Health & Managed Care practice, Wiedner & McAuliffe attorneys in our Chicago and St. Louis offices have successfully defended hospitals and physicians in high profile medical malpractice claims throughout the Midwest.
  • Workers’ Compensation Defense. For more than 40 years, we have been representing employers before workers’ compensation commissions and state courts in connection with workers compensation claims.
  • Workers’ Compensation Insurance Compliance
  • Real estate

Because many of our clients are intentional in scope, or conduct business abroad, we also provide international legal representation and transportation litigation services, as these needs arise.
