Partner Emeritus






Bradley W. Matthiesen is a trial lawyer, mediator, and founding partner emeritus of Matthiesen, Wickert & Lehrer, S.C. (“MWL”). Brad has 44 years of legal experience and is licensed to practice law in Wisconsin and Arizona. He is also admitted to practice in the Eastern and Western Districts of the State of Wisconsin and the United States Supreme Court. Brad has litigated many construction defect, personal injury, insurance coverage, toxic tort, lemon-law, and Magnuson-Moss warranty cases for individuals and insurance companies throughout Wisconsin.

Brad obtained his undergraduate degree from the University of Wisconsin-Madison in 1975. In 1978, Brad obtained his law degree from the University of Puget-Sound School of Law (now Seattle University School of Law). Upon graduation from law school, Brad was engaged in the private practice of law for Levy & Levy, S.C. in Cedarburg, Wisconsin. In 1981, Brad became an Assistant District Attorney for Ozaukee County, Wisconsin, where he tried numerous misdemeanor and felony cases. In 1984, Brad became in-house counsel at Milwaukee Insurance Group, in Milwaukee, Wisconsin, where he continued trying hundreds of civil cases both to the court and before juries. In 1994, Brad joined Mohr & Anderson, S.C., in Hartford, Wisconsin, as a partner, and, in 2001, Brad co-founded the law firm of Matthiesen, Wickert & Lehrer, S.C. in Hartford, Wisconsin. Brad has tried numerous civil cases throughout the State of Wisconsin and has tried hundreds of cases to a jury and many more to the court in the form of bench trials. Over Brad’s 44 years of practicing law, he has been instrumental in helping to settle thousands of disputed claims and insurance litigation matters. Brad has also litigated many cases that were resolved through the mediation process.

Brad was named a 2020 Super Lawyer for Personal Injury General: Defense by the Wisconsin Super Lawyers Magazine, an award given only to the top 5% of lawyers in the State.

Brad is an AV-rated attorney and a member of the Wisconsin Association of Mediators (“WAM”) and Resolute Systems, Inc. Aside from his law practice, Brad also serves as a mediator throughout the State of Wisconsin. As a mediator, Brad’s extensive history in practicing insurance law makes him adept at breaking through the thorny issues of insurance litigation that lurk in the background, and so often prevent cases from settling. As a practicing attorney with decades of practical experience, he understands the challenges and is sensitive to the difficult issues attorneys face during settlement negotiations when they engage with opposing parties and, sometimes, even their own clients. Throughout his legal career, Brad has maintained the demeanor, character, interpersonal skills, and a mature legal judgment to effectively assist parties in resolving simple or complex disputes. Brad is available to mediate a wide range of civil matters including business disputes, professional liability, personal injury, subrogation, insurance coverage, construction, landlord/tenant, and bad faith disputes.

When Brad isn’t practicing law or mediating, he enjoys spending time with his wife and six daughters. He is also an avid Milwaukee Brewer and Green Bay Packer fan.
