District court service
On January 23, 2002, Griesbach was nominated by President George W. Bush to a seat on the United States District Court for the Eastern District of Wisconsin. This was a new seat created by 114 Stat. 2762. He was confirmed by the United States Senate on April 25, 2002, and received his commission on May 1, 2002. He became Chief Judge on October 31, 2012, and served a 7-year term until October 31, 2019. He assumed senior status on December 31, 2019.

Notable case
In November 2016, Griesbach dissented when Circuit Judge Kenneth Francis Ripple, joined by District Judge Barbara Brandriff Crabb, found that the high number of wasted votes created by the 2011 Wisconsin State Assembly redistricting was unconstitutional partisan gerrymandering. The opinion was vacated and remanded by the United States Supreme Court on June 18, 2018.
