Editor's Review

VerifiedLawFirms editorial

Focus and where the firm works

Personal injury work sits at the center of this practice. The firm says it opened its doors in 1991, which puts its run past the 30 year mark. It serves clients across three states: North Dakota, Minnesota, and Montana.

That reach runs from three offices. Two sit in North Dakota, in Fargo and Bismarck. The third is in Detroit Lakes, Minnesota. The spread lets the firm cover communities on both sides of the state line, which matters in a part of the country where people cross it often for work and daily life.

The firm frames its work around litigation. In my opinion, that framing fits the case types it lists, most of which turn on proving fault and pursuing recovery for an injured person.

The range of cases it handles

The firm lists a wide set of personal injury matters, and road cases feature heavily. It handles car accidents, truck accidents, and motorcycle accidents. It also takes rideshare and bus collisions, along with recreational vehicle accidents.

Away from the road, the firm lists brain injuries, wrongful death, and premises liability. It handles nursing home injuries and dog bites. Farm and construction accidents appear on the list, as do oilfield injuries, which track a region where that work runs deep.

Medical cases form a separate group. The firm names medical malpractice, medication errors, and misdiagnosis. Product cases sit alongside them, covering defective and dangerous products. The firm also lists insurance matters, professional liability, and commercial litigation, which widens the picture past bodily injury alone.

Taken together, the list leans toward serious injury: crashes involving large vehicles, harm inside care facilities, and errors in medical treatment. Cases like these often put insurers and hospital systems on the other side, which fits a firm that describes its work as litigation.

How the team is built

The site names five attorneys, each listed as an attorney with the firm. The group works across the offices, with some based in Fargo and at least one in Bismarck.

The attorneys the site names

Duane A. Lillehaug earned a bachelor's degree from North Dakota State University in 1971 and a law degree from the University of North Dakota School of Law in 1975. He has practiced with the firm since 2004. His work covers personal injury, insurance, and business matters, which gives the team a lawyer with decades behind him.

James R. Hoy studied business management and completed an MBA at the University of North Dakota, then finished law school there in 2011. During law school he served as Editor in Chief of the North Dakota Law Review and as president of the Student Trial Lawyers Association. He worked as a law clerk after graduating, a common early step for lawyers who go on to litigation.

Lindsay M. Wilz practices from the Bismarck office. She handles general plaintiff personal injury matters and graduated from the University of North Dakota School of Law in 2012. Kellen B. Bubach works from Fargo, with a focus that includes medical malpractice and general personal injury cases.

Hannah Wegner Brink is also named among the attorneys. The pages reviewed here listed her with the team but did not carry further detail, so this listing notes her role and leaves it there.

Depth of experience across the group

The firm states that its attorneys hold more than 150 years of combined experience. That number describes the group, not any one lawyer. Read that way, it points to a mix of senior and newer attorneys sharing the workload.

The named lawyers support that reading. Lillehaug's law degree dates to the mid 1970s, while Hoy and Wilz came through law school in the 2010s. As a reviewer, I read that range as a practice that has kept bringing in lawyers rather than resting on its start.

How to read this listing

VerifiedLawFirms puts evidence ahead of advertising, so this listing stays with what the firm publishes about itself. The firm keeps channels on Facebook, LinkedIn, and YouTube, which gives someone checking it out more than one way to see how it presents its work.

What comes through is a clear subject: personal injury on the plaintiff side, across North Dakota, Minnesota, and Montana. The named attorneys, the stated start in 1991, and the three offices give the listing concrete points to stand on. For anyone weighing a firm in this region, that combination is worth a look, and the details here come straight from the firm's own pages.
