Firm Information

Overview

At Alvine Law Firm, LLP, we serve clients from our offices in Sioux Falls and Mitchell, South Dakota, offering dedicated representation across personal injury, workers' compensation, criminal defense and litigation matters. Over the years, we have secured tens of millions of dollars in recoveries for injury victims throughout the region, a track record built on preparation, persistence and genuine care for the people we represent.

When someone is harmed by another party's negligence or careless conduct, the consequences often extend far beyond the physical, touching finances, employment and family stability. We step in as advocates who understand what is at stake, standing firmly against the corporations and insurance companies that too often try to minimize a victim's claim. Our approach is direct, informed and unapologetically committed to the people who trust us with their cases.

In the workers' compensation arena, we help injured employees secure the benefits they are entitled to under the law, ensuring they are not shortchanged by employers or carriers looking to limit payouts. Our criminal defense team brings substantial trial experience, including capital and homicide cases, alongside insight from a former prosecutor who understands both sides of the courtroom. This dual perspective sharpens our strategy and strengthens every defense we mount.

Beyond these areas, we handle a broad range of litigation, representing clients in construction, business, and estate and trust disputes throughout Minnehaha County, Davison County and the surrounding South Dakota communities. We are not quick to settle simply for convenience; instead, we prepare every case as though it may go to trial, because that readiness often produces the best outcome for our clients.

We accept credit cards, offer virtual appointments and provide free initial consultations, making it easier for clients across South Dakota to reach us. Contact Alvine Law Firm, LLP, today to discuss your case.
