Mark J. Goldstein, President

Mark graduated from the University of Wisconsin Law School and has over 25 years of legal experience—in the courtroom, employing strategies for staying out of court, and with transactional matters. He created Goldstein Law Group in 2008 after more than 15 years of practice. Mark is a frequent speaker and author on topics ranging from labor and employment law to business planning and change and process management. Mark is also actively involved in various boards and civic organizations. As a result, his approach to legal issues is shaped not only by over two decades practicing law, but also by considerable experience “on the other side of the desk,” all of which works to the benefit of the firm’s clients.

  • Favorite Milwaukee spot: The Oak Leaf Trail (and all the great stops along the way).
