We provide professional representation in the following areas:

Personal Injury

Injuries sustained in an accident can affect every aspect of your life, making daily tasks and maintaining employment difficult or even impossible. Navigating the world of insurance can be scary, especially when insurance companies undervalue your case and refuse to compensate you fairly.

The attorneys at Olivier Miles Holtz have devoted their careers to advocating for injured victims helping guide them through litigation. Personal injury matters we handle include:

Automobile Accidents

Bus Accidents

Motorcycle Accidents

Truck Accidents

Texting and Driving Accidents

Business Litigation

Owning a business can be exciting and cause anxiety at the same time. Most people want to focus on their business and do what they are good at rather than figuring out  legal issues that intersect with their business activities. The attorneys at Olivier Miles Holtz represent a wide variety of business ranging from small family owned companies to large corporations. The firm has been involved in a variety of complex litigation including:


Shareholder Disputes





Olivier Miles Holtz will work with you to resolve complex business disputes, so that you can keep your business running without the stress of a lawsuit. Our dedicated team will stand by you through each stage of litigation, allowing you to focus on what is important in life rather than worrying about a lawsuit.

Criminal Defense

Most people are stunned, fearful, and often of unclear mind when approached by an officer. This occurs whether or not the party has committed a wrongful act. It is simply the status of the enforcer’s position. If an officer does detain you and asks you questions, you may be recorded. It is so easy for a person to say the wrong thing, to misstate a fact, or to arrive at incorrect conclusions.

Officers have been trained to elicit admissions and confessions and to gather evidence to prove allegations. It is not frowned upon for an officer to tell a lie in order to convince the citizen under investigation to provide a needed statement. An officer can use trickery by pretending to be one’s friend or play down the alleged crime. Sometimes, the police invite a citizen to voluntarily visit the police station to discuss a potential investigation and attempt to obtain statements that are later used to incriminate you.

As a result, whether you are facing charges or are under investigation, it is imperative that you get the right attorney involved early in the process, prior to speaking with law enforcement. This can make a significant difference in the outcome of your case.

The lawyers at Olivier Miles Holtz have extensive experience in the full spectrum of misdemeanor and felony charges in both State and Federal Court. Whether the charges involve an alcohol or drug related offense, such as a DUI (driving under the influence), possession of marijuana or even a more serious drug offense, such as possession or distribution of a controlled substance, our lawyers will defend you zealously every step of the way. We also have extensive experience with charges, including but not limited to, murder, manslaughter, assault and other violent crimes, sex offenses, white collar crimes, theft/embezzlement type crimes, DUIs and other driving crimes.

We understand the severe consequences criminal charges can have on you and your loved ones, including but not limited to sizable fines, prison or jail-time as well as a criminal history that may substantially affect your future goals and employment. We take all charges or potential investigations very seriously and vow to aggressively defend you for the best possible outcome in your case.

Workplace Injuries

Workplace injuries are all too common. If you get hurt on the job, your employer is required to pay you workers’ compensation benefits. The  lawyers at Olivier Miles Holtz are skilled at helping injured workers establish their entitlement to workers’ compensation benefits. These benefits include payments of medical expenses, pharmaceutical expenses, a portion of their weekly wages, total temporary disability benefits, total permanent disability benefits, partial permanent benefits, and other benefits allowed by South Dakota state law.

It’s important as an injured worker to know your rights. South Dakota’s worker compensation laws are complex, but the attorneys at Olivier Miles Holtz will help you navigate any claim you may have as a result of a workplace injury.

Estate Litigation

Our attorneys combine in-depth understanding of trust and estate law with experience in litigation procedure and tactics, much of which is unique to trust and estate disputes. The end result is a more expert, more efficient and more responsive advocate.

Our experience includes litigating trusts and probated disputes involving claims for breach of fiduciary duty, claims for breach of duty of loyalty, environmental claims, investment claims, beneficiary disputes, contested heirship, pretermitted and adopted heirs, charitable pledge disputes, disputed creditor claims, judicial construction and modification of wills and trusts, will and trust contests, will and trust validity, capacity, undue influence, elder abuse, contested powers of attorney, contested accountings, fraudulent transfers, partition actions, spousal right of election, wrongful death recovery, family and estate management disputes, conservatorships and guardianships, among other issues.

Child Injury or Abuse

It goes without saying that the injury or death of a child is traumatic, and, in some cases life changing. When the injury is intentional or could have been prevented, the situation becomes even more devastating. We understand the significant suffering that a child’s injuries can impose on a family and the worry and pain that parents endure in these situations.

Our lawyers have dedicated a significant portion of their careers to advocating for children. They can provide you with the legal support necessary to handle your child’s case.
