William D. "Bill" Sims co-founded Northern Plains Justice with attorney Jeff Cole in 2018, following a successful stint as a partner at a prominent Sioux Falls law firm. He brings a wealth of experience in criminal and civil cases. Bill's practice focuses on helping people who have been injured in all types of accidents be compensated for what they've lost and assisting small businesses in managing their legal disputes. Bill is licensed to practice in both South Dakota and Iowa.

Bill's Legal Experience: Bill is an honors graduate of Evangel University and the Drake University Law School. After graduation, he was commissioned as an officer in the United States Air Force, where he served as a Judge Advocate, prosecuting and defending military crimes. He continues to serve our state and country as an officer in the South Dakota Air National Guard. He has also served as an Adjunct Professor of Military Law at the University of South Dakota School of Law.

Bill in His Own Words:

"I'm proud to serve as an advocate for those facing The System-a complex network of insurance adjusters, investigators, computer systems, and lawyers that claim to "help" while all-too-often failing to do so."

"My philosophy on representing clients is simple: fight for what is right. I can't guarantee a perfect outcome of a matter, but I can guarantee we will work to solve the many problems you are facing. You will be treated with the respect and dignity you deserve. Questions will be answered and rights will be vigorously upheld. Throughout any case, you will likely experience a lot of ups and downs, and we'll be there to guide you through them."
