Michael B. Brennan joined Gass Weber Mullins LLC in December 2008.  He tries cases and handles appeals in federal and state courts, primarily in the area of commercial litigation.

Brennan returned to private practice with the firm after serving 9 years as a judge on the Milwaukee County Circuit Court where he presided over nearly 300 trials and thousands of motions.  He was the presiding judge of the Civil Division of that court.  In 2005 he was affirmed more often than any other judge in the State of Wisconsin.  He continues to serve as a reserve judge in Wisconsin.

Brennan has published over 30 articles on federal practice and procedure, criminal sentencing, and other topics in a variety of law reviews, newspapers, and other periodicals including The Wall Street Journal, Milwaukee Journal Sentinel, National Review, New Republic, Wisconsin Lawyer, and the Illinois Bar Journal.  Those articles have been cited numerous times in the Wisconsin Statutes, various legal treatises, and other law review articles.  He has also given more than 40 speeches and continuing legal and judicial educational presentations throughout Wisconsin and surrounding states.

Brennan obtained his Bachelor of Arts cum laude from the University of Notre Dame, and graduated from Northwestern University School of Law where he served as an editor on the law review and was the moot court champion.  He served as a law clerk to the late Chief Judge Robert Warren of the U.S. District Court for the Eastern District of Wisconsin, and as a law clerk to Judge Daniel Manion of the U.S. Court of Appeals for the Seventh Circuit.

Brennan also served as an Assistant District Attorney in the Milwaukee County District Attorney’s office where he prosecuted felony and misdemeanor cases and first-chaired approximately 60 trials.  During this time he was also staff counsel to a committee that rewrote Wisconsin’s statutes to implement Truth-in-Sentencing.

In 2002 The Milwaukee Business Journal named Brennan one of its “40 under 40” professional leaders.  He received a special Commendation from the U.S. Department of Justice for his service as a member of the National Advisory Committee on Violence Against Women.  He also served as a public member of the Wisconsin Legislative Council’s Special Committee on Crimes against Children.
