Matthew Naasz is a partner at Gunderson, Palmer, Nelson and Ashmore, LLP’s office in Rapid City, South Dakota. His practice areas include business law, governmental law, administrative law, insurance and litigation.

Growing up in Aberdeen, South Dakota, Matthew developed an interest in the law at a young age. Once he graduated from high school, Matthew spent the next four years in the United States Army. After finishing his military career in 1998, Matthew attended undergraduate at Northern State University and received a bachelor’s degree in English. With a writing background, Matthew was able to excel in Law School, serving as the Copy Editor of Law Review and graduating as a Sterling Honor graduate. He graduated from Law School at the University of South Dakota in Vermillion in 2006.

Matthew came to Gunderson, Palmer, Nelson & Ashmore, LLP after graduating. Nearly four years later, he accepted the opportunity to work as a Staff Attorney for the South Dakota Supreme Court. In January 2013, Matthew went to work as an Assistant Attorney General in Pierre. There, he worked in the Appellate Division and wrote for the Supreme Court, eventually moving into civil litigation—specializing in tax litigation, water resources law, environmental issues, and civil rights. Now, Matthew and his family have ventured back to Rapid City, a place they are happy to call home.

Although Matthew’s experience is vast—specializing in Civil Litigation, Commercial Litigation, Insurance Defense, Administrative Law, and Environmental Law—he maintains focus with an impressive work ethic. Matthew’s maturity as a partner and knowledge of administrative processes are valuable to the GPNA team.
