Catherine is an attorney with Gunderson, Palmer, Nelson, and Ashmore, LLP’s Pierre Office. Her practice areas include Business Law, Governmental, Administrative and Municipal Law and Estate Planning and Probate.

Catherine A. Seeley grew up in southeastern South Dakota and developed a love of learning at an early age. After graduating high school, Catherine attended the University of South Dakota and graduated with a bachelor’s degree in English education. She then moved to central South Dakota where she enjoyed teaching middle and high school English for four years. Catherine’s love of learning drove her to seek advanced degrees, and she returned to the University of South Dakota to pursue a law degree and a master’s degree in adult and higher education.

While pursuing her joint degrees, Catherine took advantage of several opportunities to better herself. In law school, Catherine refined her oral advocacy and writing skills by participating on the USD School of Law Moot Court Board. She also took on various leadership roles, serving as a board member on student organizations and as her class’s treasurer. Catherine graduated at the top of her law school class and was honored to receive the Gavel Award at graduation as the faculty voted her “outstanding student.”

Following law school, Catherine returned to central South Dakota with her husband and had the privilege of serving as a law clerk for the Honorable Roberto A. Lange, Chief Judge of the United States District Court for the District of South Dakota. Clerking gave Catherine the opportunity to work on a variety of complex and challenging legal issues.

Catherine joined Gunderson, Palmer, Nelson, and Ashmore, LLP’s Pierre Office following her clerkship, and she looks forward to helping clients with their various legal needs. Catherine has come to realize that a career as a lawyer provides the greatest opportunity for lifelong learning. 

Outside of work, Catherine enjoys spending time with her husband Derek and their two Labradors. They especially enjoy spending time with family, hiking, and watching their favorite sports.
