Introduction
Grant Alvine graduated from the Gerry Spence Trial Lawyers College in 2001, an intensive trial advocacy program known for producing attorneys who try cases rather than settle them reflexively, and that training has defined the character of the firm he leads. Alvine Law Firm, LLP has operated in South Dakota since 1988, building a record of seven-figure results for clients injured in accidents, construction sites, and workplaces across the state.
The firm maintains two offices: 809 W 10th St, Sioux Falls, SD 57104, reachable at 605-275-0808, and 519 N Main St, Mitchell, SD 57301, reachable at 605-292-0809. The Sioux Falls office anchors the firm in South Dakota’s largest city; the Mitchell office extends access across the central part of the state. The website is https://alvinelaw.com.
Practice Areas
Personal Injury: The firm handles the full spectrum of personal injury claims in South Dakota. This includes car accidents, motorcycle accidents, truck accidents, product liability cases, bad faith insurance claims, slip and fall injuries, pedestrian accidents, and wrongful death. Each of these case types demands a different combination of investigative, medical, and legal expertise.
Motorcycle accidents merit particular attention at Alvine Law. Grant Alvine and attorney Zachary T. Flood both ride motorcycles themselves. That personal experience is not incidental: attorneys who understand how motorcycles handle, how drivers of other vehicles typically fail to see or yield to motorcyclists, and what riding conditions produce specific injury patterns bring a different quality of preparation to these cases than those who have never ridden. The Sturgis Motorcycle Rally, held every August in the Black Hills, draws approximately 450,000 riders. The concentration of motorcycles on South Dakota roads during and around the rally produces a predictable increase in accident claims, and the firm has specific expertise in rally-related incidents.
Workers’ Compensation: South Dakota workers’ compensation law includes time limits that can extinguish a valid claim if not observed. Injured workers who miss seven or more workdays should seek legal advice promptly. The firm has obtained significant workers’ compensation results, including a $575,000 award for a client whose workplace injury would otherwise have been undervalued.
Criminal Defense: The firm handles DUI cases and drug charges, areas of criminal defense where the procedural stakes are high and the consequences of inadequate representation can be severe.
Estate and Trust Disputes: Disputes over wills, trusts, and estates require a different legal skill set but the same commitment to thorough preparation and clear advocacy. The firm handles these matters for clients whose inheritance rights or fiduciary obligations are in question.
Construction Disputes: Construction projects generate contract disagreements, defect claims, and liability questions that require legal counsel familiar with the industry’s particular practices and documentation standards.
Attorney Profiles
Grant Alvine brings more than 25 years of legal experience to the firm he leads. Before entering private practice, he served as a law clerk in the Fifth Judicial Circuit and as a prosecutor in the Minnehaha County State’s Attorney’s Office. Prosecutorial experience translates directly into trial competence: prosecutors try more cases to verdict in a few years than most civil attorneys try in a career. Grant Alvine supplemented that foundation with the Gerry Spence Trial Lawyers College in 2001, a program that emphasizes authentic courtroom advocacy and preparation for trial rather than settlement. He is listed in Super Lawyers and recognized by the National Trial Lawyers as a Top 100 attorney. He is also an avid motorcyclist, a background that informs his representation of motorcycle accident clients.
Zachary T. Flood focuses on personal injury cases and also rides motorcycles. His shared experience with the clients he represents in motorcycle accident cases gives him a ground-level understanding of the dynamics involved in those incidents.
Mark J. Welter is a partner at the firm, contributing to its overall practice capacity and client service.
Sam Alvine serves as an associate, adding depth to the firm’s legal team.
Case Results
The firm’s record of results includes:
- $2,000,000 construction accident settlement
- $1,750,000 elevator collapse settlement
- $575,000 workers’ compensation award
- $500,000 insurance bad faith settlement
- $500,000 pedestrian accident settlement
These figures represent the upper end of the firm’s documented outcomes. Not every case produces a seven-figure result, and past outcomes do not guarantee future ones. What they demonstrate is the firm’s capacity to take serious cases through the full claims process and achieve meaningful compensation.
Location and Service Area
The Sioux Falls office at 809 W 10th St serves eastern South Dakota and functions as the firm’s primary location. Sioux Falls is the state’s largest city and the center of its commercial and legal activity.
The Mitchell office at 519 N Main St extends the firm’s geographic reach into central South Dakota. Mitchell sits along I-90, making it accessible to clients from a broad swath of the state’s interior.
The Sturgis Motorcycle Rally brings hundreds of thousands of riders to western South Dakota each August. The firm’s expertise in rally-related accident claims means out-of-state riders who sustain injuries in South Dakota have access to counsel who understands both the legal landscape and the riding context.
Client Focus
Alvine Law Firm represents individuals who have been injured through others’ negligence, workers hurt on the job, people facing criminal charges, and families dealing with estate or construction disputes. The common thread across these different matters is the client’s need for an advocate who will prepare thoroughly and pursue the best available outcome.
The firm’s two-office footprint reflects a commitment to geographic accessibility. South Dakota is a large, sparsely populated state, and having counsel available in both Sioux Falls and Mitchell reduces the burden on clients who would otherwise need to travel significant distances for legal representation.
