Gimbel, Reilly, Guerin & Brown: Our History
In 1968, after arguing some of the most high profile cases of the day as a federal prosecutor for the Eastern District of Wisconsin, Franklyn M. Gimbel founded the firm. Frank’s late brother, Stanley P. Gimbel, joined a year later, followed by former federal prosecutors Richard E. Reilly and Thomas E. Brown, and former Department of Justice Special Agent D. Michael Guerin.
The firm has continued to build upon this strong base of attorneys, adding the experience of Denis J. Regan, Kathryn A. Keppel, Patrick J. Knight, and Raymond M. Dall’Osto in the 1980s and Christopher L. Strohbehn, Erin M. Strohbehn, Steven C. McGaver and Jason D. Luczak in the 2000s.
Today, GRGB is recognized as one of the best trial and litigation firms in Wisconsin. Our attorneys have successfully represented individuals and businesses in a wide variety of cases, from white collar criminal investigations and serious criminal offenses, to personal injury and complex civil litigation, to family law and real estate matters.
