Her academic background reflects sustained study of legal systems, public policy, and criminal justice. Before law practice, she worked as a research analyst and as a financial crimes analyst, investigating money laundering, tax fraud, elder financial abuse, and other financial crimes. This combination of research and legal training supports detailed analysis in employment, regulatory, and litigation matters.

Kristin clerked for the South Dakota Supreme Court after law school and then for the U.S. District Court for the District of South Dakota. In those roles, she assisted judges with legal opinions across a wide range of civil and criminal cases and stages of litigation. She joined Boyce Law Firm in 2022. Her practice now includes employment law, workers’ compensation, administrative matters, appeals, commercial and insurance litigation, family law, trusts and estates, health care issues, and utility matters.

Kristin N. Derenge serves on the Board of Women in Law for the Sioux Falls area chapter and supports efforts that encourage legal careers and professional development. Her clerkships in state and federal courts give her practical insight into judicial decision-making and written advocacy. She uses that background to help clients organize complex facts, understand procedural requirements, and evaluate legal options in employment matters, regulatory proceedings, appeals, workers’ compensation issues, and civil litigation that can involve several overlapping areas of law.
