Nelson L. Mitten

Nelson L. Mitten,

Nelson L. Mitten’s areas of practice include civil trials and civil appeals primarily in the areas of general commercial law, commercial torts, creditor’s rights, real estate, and employment litigation. Nelson has been lead counsel for trials and appeals at all levels of both the state and the federal court systems. Many of the successful appeals have resulted in new substantive law being made, including the decision in Investors Title Company v. Hammonds, 218 S.W.3d 288 (Mo. 2007), in which the Missouri Supreme Court held that a subdivision of County government may be liable in a suit for quantum meriut because such a claim was contractual in nature, and therefore sovereign immunity was not applicable.

Nelson is licensed in Missouri and Illinois, in the U.S. Court of Appeals for the Eighth Circuit, in the U.S. District Courts for the Eastern and Western Districts of Missouri and in the Central, Northern and Southern Districts of Illinois.

Prior to joining Riezman Berger in 1985, Nelson served as a law clerk to the Honorable J. Waldo Ackerman, Chief Judge, U.S. District Court, Central District of Illinois, and for U.S. Magistrate Charles H. Evans, also of the Central District of Illinois. He earned his Juris Doctorate from Washington University in St. Louis, where he served as the Notes and Comments Editor for the Washington University Law Quarterly.

Nelson was named a Super Lawyer in 2006.

Active in the community, Nelson has served on the Board of Directors of the Epilepsy Foundation – St. Louis Region and the Epilepsy Foundation of America. He is a member of the Board of Directors of the Maplewood-Richmond Heights School District, having been first elected in 1998, and serving multiple terms as its President and Treasurer. Mr. Mitten has also served on the Tax Increment Financing Commissions for the cities of Maplewood and Richmond Heights.
