Kathryn works as a trial lawyer and litigation attorney in the firm’s Sioux Falls Office. She represents clients throughout the State of South Dakota, where she is licensed to practice in State and Federal Courts. Her educational background and training is in Nursing. She earned her Bachelor of Science Degree in Nursing from Augustana College in Sioux Falls and worked as a full-time critical care nurse both before and during law school. The character traits that made her an excellent nurse (a strong work ethic, compassion and kindness, and meticulous attention to detail) have also provided the foundation for her successful litigation practice that involves defending medical malpractice cases and representing medical professionals in regulatory and professional licensing matters.

Kathryn is specifically sought out by prospective clients due to her significant civil jury trial experience and her background and knowledge of medical issues, and the medical profession in general. Kathryn is still a licensed Registered Nurse but applies her special education and training in representing her clients. She is best known among her peers and her clients for her successful defense of medical malpractice cases, but her practice also includes all areas of the medical profession, including nursing home and home health care liability; medical device product-liability defense; and pharmaceutical defense. Her experience and success in litigating cases involving the medical and healthcare professions have also prompted clients to seek out her services in defending professional liability cases involving architects, accountants, and attorneys, and complex civil litigation cases.

Kathryn is among a group of select trial attorneys elected to membership in the American Board of Trial Advocates (ABOTA). She holds an AV rating from Martindale-Hubbell and is also a member of the Defense Research Institute (DRI), as well as the South Dakota Defense Attorneys Association and the South Dakota Trial Lawyers Association.

Outside of work, Kathryn enjoys spending time with her family. Together with her children, Kathryn is also a small business owner and operator of a rental property and self-storage business. Establishing and being part of a family-owned business has given her unique personal insight into the legal issues that challenge small businesses.
