In 2007, Matt took a pro bono case to trial, challenging a self-storage company’s sale of a local family’s belongings for the paltry sum of $600. When the client went in to pay the bill and found out her property had been auctioned off without any notice, she was told to “get a lawyer.” It was good advice. After a week-long trial, the jury awarded $20,000 in damages and $100,000 in punitive damages. In response, the company, the largest self-storage company in the world, changed its practices nationwide to ensure customers receive fair treatment. The verdict was upheld on appeal. Cook v. Public Storage Corp., 2008 WI App 155. Matt was awarded the 2008 Exceptional Pro Bono Advocacy Award by Legal Action of Wisconsin for his work on the case.
