Sheldon Oppermann


Sheldon has a reputation in the business community for innovation, integrity and delivering results. He has a passion for helping others accomplish their objectives and problem solving. His broad range of previous experience can help facilitate a wide range of business transactions because he understands the difference between business risks and legal risks and can help you manage both.

Before getting his law degree, Sheldon worked extensively in commercial real estate development, construction, property management, leasing, and financing. His experience has been in the day to day operations of businesses. Now that he has joined Mallery & Zimmerman he is able to combine that practical experience with sound legal advice.

Prior to his current role, Sheldon was responsible for the financial operations of a large Milwaukee area architecture and real estate development firm. This experience has given Sheldon an in-depth understanding of the many ways to manage financial goals and helps him not only be an advisor, but also a facilitator.
