Redstone Law Firm is excited to announce former partner James E. McMahon’s return to Redstone Law Firm LLP.  Jim will be working on litigation matters, as he has his entire career, in an Of Counsel role with Redstone Law Firm.

Jim earned his bachelor's degree from Morningside College in Sioux City, Iowa, and a law degree from the University of South Dakota.  Throughout his legal career, Jim has represented plaintiffs and defendants with distinction. He served as an Assistant Attorney General from 1978-1981 and then joined the Sioux Falls-based law firm of Boyce, Murphy, McDowell and Greenfield, where he practiced as a trial lawyer. In 2002, he was honored with the appointment for confirmation as U.S. Attorney for South Dakota by President George W. Bush.  After serving as U.S. Attorney, Jim returned to private practice at Murphy, Goldammer and Prendergast LLP, which later changed its name to Redstone Law Firm.  Jim retired from the full-time practice of law in 2019 to spend time with his wife Kathy, their children and grandchildren, but missed his legal career.

During his career as a trial attorney, Jim has received a number of honors for his work as a trial lawyer, including being named South Dakota Trial Lawyer of the Year, and he received the Richard S. Arnold Award for Distinguished Service and Lifetime Achievement from the Eight Circuit Court of Appeals Bar Association.  Jim has been a member of the American College of Trial Lawyers and the American Board of Trial Advocates for many years.

Redstone's experience and vision uniquely position us to meet the challenges of a changing world, and Jim embodies these values. We remain committed to our core values, and our five practice areas: business law, estate planning, trust and estate administration, government relations, and litigation.
