Chris Avallone Co-Chairs von Briesen’s Appellate Section and is a member of the Commercial and Business Litigation Section. He has represented a wide variety of clients in both the Wisconsin Court of Appeals and Supreme Court, as well as the Seventh Circuit Court of Appeals. In his commercial practice, Chris represents a diverse group of clients in complex civil litigation, with an emphasis on disputes between the shareholders or members of privately-held companies, breach of contract actions, and class action defense. At all stages of litigation, Chris uses his strong writing skills and “big-picture” mentality to distill complex facts and tell his client’s story, inform the court of the law, and – when necessary – argue for a change in the law.

Chris is well-versed in the use and legal implications of artificial intelligence (“AI”). Chris advises clients on using AI and helps them to develop internal policies on the use of AI. As a member of von Briesen’s task force on AI, he has spoken on the topic to internal and external audiences. In his practice, he responsibly deploys large language models to increase efficiency and drive better outcomes for his clients. 

Chris is active in both the community and pro bono service. Chris has obtained excellent results in multiple federal civil rights actions on behalf of incarcerated individuals. In the greater Milwaukee community, Chris serves on the Board of two non-profit organizations, Milwaukee Riverkeeper and Project Return. Milwaukee Riverkeeper is a science-based advocacy organization working for swimmable, fishable rivers throughout the Milwaukee River Basin. Project Return is a non-profit that provides a wide array of services to people after incarceration. 

Before joining von Briesen, Chris served as a law clerk to Justice Shirley Abrahamson of the Wisconsin Supreme Court. He graduated Order of the Coif from University of Wisconsin Law School. During law school, Chris served as a judicial extern to U.S. District Judge Barbara Crabb. He also completed internships with the United States Department of Interior, Office of the Solicitor and University of Wisconsin Law School Consumer Law Litigation Clinic.
