Mark Gundrum (born March 20, 1970) is an American lawyer and politician serving as a judge of the Wisconsin Court of Appeals for District II.[1] He previously served as a member of the Wisconsin State Assembly from 1999 to 2010.
Born in Milwaukee, Wisconsin, Gundrum graduated from Catholic Memorial High School, where he played for the school's gridiron football team.[2] He received his bachelor's and law degrees from the University of Wisconsin–Madison.[3]
Gundrum served on the Hales Corners, Wisconsin village board. He later worked as a staff attorney for Rudolph T. Randa, a judge for the United States District Court for the Eastern District of Wisconsin.[4] He joined the United States Army Reserve in 2000, and was deployed to Iraq in 2008.[5]
In 1998, Gundrum won the race to succeed Mary Lazich in the Wisconsin State Assembly as a Republican.[6] In the 2002 election, he defeated fellow state legislator Marc C. Duff, who ran against Gundrum due to redistricting.[7] While serving in the Wisconsin State Assembly, Gundrum worked with Steven Avery, who was exonerated after being falsely convicted of a sexual assault, to pass a criminal justice reform bill.[8] In 2010, Gundrum was elected as a Circuit Court judge for Waukesha County. He was soon thereafter appointed by Governor Scott Walker in 2011 to fill a vacancy on the Wisconsin Court of Appeals.[9] Gundrum successfully ran for the seat in 2013 and was re-elected in 2019.[10]
Gundrum was named as one of Governor Scott Walker's finalists to replace Justice David Prosser, Jr. on the Wisconsin Supreme Court in June 2016.[11]
Gundrum and his wife, Mary, married in 1996. They are Catholic and have eight children, whom they homeschooled through Wisconsin Virtual Academy. Their youngest child was born with encephalocele and a facial cleft, which required surgery to correct at Boston Children's Hospital.[12] Gundrum appeared in the 2015 Netflix documentary series Making a Murderer, detailing Avery's case.
