Attorney John Mayer is a founding partner of Mayer, Graff & Wallace.

John then pursued his Juris Doctor at Creighton Law School in Omaha, Nebraska. After taking the Wisconsin Bar Exam, he began his career in one of Wisconsin’s top medical malpractice and insurance defense firms.
Over the years, the legal landscape changed and John was quick to adapt and thrive. He began to take on more personal injury cases, contract disputes, and commercial litigation. After over 30 years in practice, John felt that there was a need for impassioned advocates to represent “the little guy”. Thus, MGW Law was born.

John’s career is well-rounded having spent time on both sides of the aisle. He has successfully prosecuted and defended hundreds of matters, including a multitude of 7 and 8 figure cases for both individuals and institutional clients. He has pursued dozens of matters to verdict in areas including complex business litigation, medical malpractice, insurance litigation, and many others, and has successfully litigated matters all the way to the Wisconsin Supreme Court. His hard work and dedication to his clients has resulted in the recovery of tens millions of dollars for his clients throughout the years, including obtaining what is thought to be the largest award of punitive damages in Manitowoc County’s history. He is licensed to practice in Wisconsin, the United States District Court for the Eastern District of Wisconsin, the United States District Court for the Western District of Wisconsin, the United States Court of Appeals for the Seventh Circuit, and the Supreme Court of the United States.
Beyond the courtroom, John has given presentations to audiences that include lawyers, health care providers, insurance personnel, classrooms, and other institutions on topics ranging from evidentiary matters, insurance law, medical malpractice, negligence, wrongful claims denials, and much more.
