Zachary Willenbrink

Zach Willenbrink is a member of Godfrey & Kahn’s Litigation Practice Group in the firm’s Milwaukee office.

Zach represents clients in many types of litigation and disputes—from pre-filing to pre-trial, trial and appellate phases—primarily those involving complex commercial, intellectual property, insurance trade practices, international law and media and entertainment issues. 

Zach enjoys untangling complex legal and factual issues, in order to understand what is truly at issue in a dispute and working toward the best resolution possible. A former member and songwriter in several touring bands, Zach tries to approach disputes creatively, whether in writing briefs, approaching settlement, or thinking strategically about the best way to reach a favorable outcome in a case.

In addition, Zach accepts a variety of pro bono legal matters, including representation of state prisoners in civil rights appeals to the Seventh Circuit and work with the Eviction Defense Project in Milwaukee County Circuit Court.

Prior to joining Godfrey & Kahn, Zach spent more than four years as a law clerk with Judge J.P. Stadtmueller of the Eastern District of Wisconsin. Before that, Zach graduated magna cum laude from Marquette University Law School. At Marquette, Zach was co-president of the Public Interest Law Society and Marquette’s chapter of the American Constitution Society. He served as a research assistant to Senator Russ Feingold and Dean Joseph Kearney, interned with Judge Lynn Adelman of the Eastern District of Wisconsin and volunteered with Marquette’s Volunteer Income Tax Assistance program.
