In 1878, Frank L. Boyce arrived in Sioux Falls and established one of the city’s oldest law firms. According to George Kingsbury’s History of South Dakota, “Mr. Boyce was so well pleased with Dakota and so impressed with its future possibilities that he concluded to make this city his future home.”
When Frank Boyce arrived, Sioux Falls was just beginning to experience the boom that would make it the “Queen City of the Dakotas.” The downtown consisted of just one street, Phillips Avenue, lined with one- and two-story frame buildings with false fronts. Sioux Falls was a growing city, and Boyce’s firm thrived alongside it.
From our restored 1928 Wintersteen Building at the corner of 11th and Main, we carry forward the tradition Frank Boyce established. The landmark building, originally the Wintersteen Chevrolet showroom, underwent extensive renovation that earned the 2013 Mayor’s Historic Preservation Award.
Over 145+ years, we’ve guided clients through economic changes, legal evolutions, and countless personal milestones. What hasn’t changed is our dedication to the people and businesses of South Dakota. We believe that Frank Boyce would be proud of the firm he founded and the City and State he chose to call home in 1878.
Our lawyers and support team bring sophisticated legal knowledge combined with deep understanding of South Dakota life. We know the local courts, the business climate across the state, and the values that matter to our clients, whether you’re in Sioux Falls, Rapid City, Aberdeen, Mitchell, or anywhere across South Dakota.
We believe the best legal relationships are built on trust and clear communication. From your first consultation through resolution, we explain options in plain language, respect your time, and keep you informed every step of the way. Whether you need trust and estate planning, business counsel, or litigation representation, our collaborative approach means you get comprehensive solutions informed by diverse legal perspectives.
Our commitment extends throughout the community. We serve on nonprofit boards, support local charities, and mentor the next generation of legal professionals through partnerships with the University of South Dakota School of Law. We work with organizations like the Chamber of Commerce, United Way, and Development Foundation to support regional growth.
That commitment to excellence doesn’t go unnoticed. The recognitions our attorneys receive carry real weight because they aren’t self-submitted or purchased. They are earned through peer nominations, independent research, and direct client feedback. When Best Lawyers, Super Lawyers, Martindale-Hubbell, and Chambers & Partners recognize a Boyce Law Firm attorney, it means other lawyers and clients are vouching for their skill, character, and dedication.
Year after year, multiple Boyce Law Firm attorneys across a wide range of practice areas receive these honors. That consistency across the entire firm reflects something deeper than individual achievement. It reflects a shared culture of excellence, integrity, and genuine care for the people we serve.
We’re proud of these recognitions, but what matters most to us is the trust our clients place in Boyce Law Firm every day. To learn more about our attorneys and their individual accomplishments, we invite you to meet the team.
