Maslon Celebrates 80 Years of Dedicated Service to Clients in Minnesota and Nationwide

Maslon, one of the largest law firms in the state, is proud to celebrate its 80th anniversary in 2026.

Maslon’s founding story is one of considerable challenges and fierce determination—anchored by a profound commitment to Minnesota.

Upon graduating from Harvard Law School in 1923 and clerking for U.S. Supreme Court Justice Louis D. Brandeis, firm namesake Samuel H. Maslon built his own successful practice as a corporate and tax attorney after he was denied opportunities at the established firms in his hometown of Minneapolis, where anti-Semitism ran deep.

Meanwhile, three other prominent Jewish attorneys, Sidney Kaplan, Hyman Edelman, and Sheldon Kaplan, formed a partnership in 1946 that expanded in 1956 to include Sam Maslon, Roger Joseph, and Marvin Borman—which then became Maslon, Kaplan, Edelman, Joseph & Borman.

Today, over 80 attorneys practice at Maslon across corporate & securities, estate planning, financial services, labor & employment, real estate, and litigation—with nationally known practices in tort & product liability, insurance recovery, and construction and real estate litigation. Individuals, closely held companies, and large multinational corporations alike trust Maslon to develop forward-looking legal strategies that will advance their most important goals.

Along with providing exemplary legal services, Maslon proudly sustains the values inspired by its founders: respecting diversity, taking care of firm members, and giving back to the broader community—including through pro bono legal service to protect both individual rights and the collective rights of the disadvantaged.

“Maslon has always been a forward-looking firm—for the clients whom we have been so privileged to serve, for our people, for our profession, and for our community,” said Firm Chair Keiko Sugisaka. “On our 80th anniversary, we reaffirm our commitment to the values that have made us who we are today, and we look forward to continuing our legacy of service and excellence to our clients and community for many years to come.”

Over the decades, Maslon attorneys have played key roles in city, state, national, and international history. Sidney J. Kaplan served as a prosecutor at the International Military Tribunal at Nuremberg following WWII, at which Nazi leaders stood trial for their crimes. Hy Edelman served in the mid-1940s on then-Minneapolis Mayor Hubert Humphrey's Council on Human Relations, which drafted the nation’s first municipal fair employment law prohibiting discrimination on the basis of race, creed, or color. Bill Pentelovitch represented plaintiffs in litigation to desegregate the Minneapolis Public Schools in the 1970s.

More recently, in 2020, after the murder of George Floyd by Minneapolis police, Steve Schleicher was asked by Minnesota Attorney General Keith Ellison to serve as pro bono special prosecutor for the state of Minnesota in the prosecution of former police officer Derek Chauvin—culminating in a six-week trial in 2021 that was broadcast worldwide. The jury convicted Chauvin on all counts, and the U.S. Supreme Court later rejected Chauvin's appeal of his conviction. Maslon was honored to support Steve and the team that assisted him—primarily Stephanie Laws and David Suchar—who dedicated more than 2,800 pro bono hours to the effort.

Other landmark matters include defending the designer of the collapsed I-35W bridge, the single most catastrophic transportation event in Minnesota; securing nearly $200 million in insurance proceeds for the settlement of the clergy abuse claims brought against the Archdiocese of Saint Paul and Minneapolis; obtaining a precedent-setting multimillion-dollar trial verdict on behalf of a class of hourly Walmart workers alleging violations of the Minnesota Fair Labor Standards Act; facilitating the transactions that established Indian gaming in Minnesota; supporting the founding and growth of some of the largest restaurant groups in the country; serving as outside general counsel to some of Minnesota’s largest nonprofit institutions; and assisting one of the country's largest financial institutions in obtaining billions of dollars of settlements on behalf of RMBS trusts it administered following the 2008 housing market collapse.

Maslon has also led the way in fostering a legal profession that reflects the rich diversity of the community it serves. In 1973, Maslon was one of the first major law firms in Minnesota to hire women attorneys; in 2003, it was the first to elect a woman, Terri Krivosha, as chair; and in 2021, with the election of Keiko Sugisaka, it was the first firm to elect a BIPOC woman to that role. Today, one-third of Maslon’s partnership and half of its leadership are women. And since 2017, the firm has given more than 320 young people from diverse backgrounds meaningful exposure to the practice of law through UPLIFT Legal Institute for Teens—a nonprofit that Maslon founded to provide free, after-school mock trial programming to middle and high school students.

In addition, Maslon is one of just a few of the largest Minnesota law firms to resist merger, a decision of which firm members are particularly proud. “After 80 years, we still believe that our independence preserves our distinct culture and creates value for clients in the form of judicious staffing, competitive rates, and tailored service,” Keiko said.

Never a firm to rest on its laurels, Maslon looks forward to many more years of serving its clients, investing in its people, and improving access to justice.
