O’Keeffe O’Brien Lyson Attorneys Review – Personal Injury, Family Law, Criminal Defense, Real Estate & Business Litigation Services
Introduction
O’Keeffe O’Brien Lyson Attorneys, found online at OkeeffeAttorneys.com, is a Fargo, North Dakota law firm providing a broad range of legal services to individuals, families, property owners, and businesses. Rather than concentrating exclusively on one legal niche, the firm operates as a multidisciplinary practice covering five major areas: personal injury, family law, criminal defense, real estate law, and business litigation.
This broad practice makes O’Keeffe O’Brien Lyson Attorneys different from firms that focus solely on accident claims or criminal cases. A client may approach the firm after a serious car accident, during a divorce or custody dispute, after being charged with a crime, while purchasing commercial property, or when facing a business-related lawsuit.
The firm's location in Fargo also gives it a strong regional focus. Its attorneys emphasize experience with the laws of both North Dakota and Minnesota, making the practice particularly relevant to individuals and businesses in Fargo, Moorhead, and surrounding communities. Its personal injury attorneys additionally state that they represent clients across North Dakota, Minnesota, and South Dakota.
From a review perspective, one of the strongest characteristics of O’Keeffe O’Brien Lyson Attorneys is the depth of services available within a single law firm. Instead of maintaining one attorney as a generalist for every type of problem, the firm divides its lawyers into teams concentrating on specific areas of law.
This O’Keeffe Attorneys review examines those services in detail and explains what prospective clients can expect from the firm.
What Is O’Keeffe O’Brien Lyson Attorneys?
O’Keeffe O’Brien Lyson Attorneys is a Fargo-based law firm serving both individual and business clients.
The firm's primary practice areas include:
-
Personal injury
-
Family law
-
Criminal defense
-
Real estate law
-
Business litigation
Within those categories, the attorneys handle numerous specific legal matters, including car and motorcycle accidents, catastrophic injuries, medical malpractice, wrongful death, divorce, child custody, adoption, DUI charges, felonies, real estate transactions, title disputes, contract disputes, corporations, partnerships, foreclosures, collections, and landlord-tenant litigation.
The firm's philosophy is centered on understanding each client's circumstances before developing a legal strategy. Rather than presenting itself as a volume-oriented operation, O’Keeffe O’Brien Lyson Attorneys emphasizes listening to clients, understanding their concerns, and building an appropriate plan for representation.
Personal Injury Legal Services
Personal injury is one of O’Keeffe O’Brien Lyson Attorneys' most substantial practice areas.
The firm's personal injury lawyers represent individuals and families who have suffered harm because of another party's negligent or careless conduct.
Cases handled by the personal injury team include:
-
Catastrophic injuries
-
Auto accidents
-
Motorcycle accidents
-
Product liability
-
Slip and fall accidents
-
Defective products
-
Medical malpractice
-
Wrongful death
-
Boating accidents
-
Other tort and litigation matters
The firm's attorneys help injured clients investigate what happened, identify potentially responsible parties, deal with insurance issues, document damages, negotiate claims, and pursue litigation when necessary.
Car Accident Representation
Motor vehicle accidents represent a significant part of the firm's injury practice.
An automobile accident can result in substantial financial and personal consequences, including medical expenses, rehabilitation costs, lost income, physical pain, and permanent disability.
O’Keeffe O’Brien Lyson Attorneys represents people injured in motor vehicle collisions and helps clients determine whether another driver or responsible party may be legally liable for their losses.
An attorney may investigate evidence such as accident reports, medical documentation, witness testimony, photographs, insurance information, and other records relevant to determining responsibility.
The firm's personal injury attorneys have experience with ordinary passenger-vehicle accidents as well as serious motor vehicle crashes involving catastrophic injuries.
Motorcycle Accident Cases
O’Keeffe O’Brien Lyson Attorneys also handles motorcycle accident claims.
Motorcycle accidents can produce particularly severe injuries because riders have considerably less physical protection than occupants of passenger vehicles.
Potential injuries can include broken bones, brain injuries, spinal damage, internal injuries, and permanent disabilities.
The firm's role is to evaluate liability, document the client's injuries and financial losses, and pursue applicable insurance coverage or litigation against responsible parties.
Catastrophic and Serious Injury Claims
One particularly important part of the firm's personal injury practice involves catastrophic injuries.
O’Keeffe O’Brien Lyson Attorneys describes catastrophic injuries as severe, life-changing, or permanent injuries that result in long-term physical or mental impairment.
Traumatic brain injuries are one example.
These cases are particularly complicated because compensation may need to account for consequences extending decades into the future, including ongoing medical treatment, rehabilitation, personal assistance, reduced employment opportunities, and permanent changes to the injured person's daily life.
For families dealing with a catastrophic injury, the firm's experience with long-term damage claims can be especially relevant.
Medical Malpractice
Medical malpractice is another major service offered by O’Keeffe O’Brien Lyson Attorneys.
Medical malpractice claims can arise when a healthcare provider's negligent conduct causes injury to a patient.
These cases are often substantially more complicated than ordinary negligence claims because establishing liability can require detailed analysis of medical records, accepted standards of care, and expert medical testimony.
The firm's attorneys represent patients and families pursuing compensation after serious injuries allegedly caused by medical negligence.
Product Liability and Defective Products
O’Keeffe O’Brien Lyson Attorneys represents consumers injured by defective products.
Its personal injury services specifically include both product liability and defective product claims.
These cases may involve questions concerning how a product was designed, manufactured, distributed, or accompanied by warnings.
Founding partner Tim O’Keeffe's practice also includes defective medical devices and dangerous or defective drugs, providing the firm with experience in more specialized product-related injury litigation.
Product liability cases can be technically complex and may require expert analysis to determine how a product failed and whether that failure caused the client's injuries.
Slip and Fall and Premises Liability
The personal injury team also represents individuals injured in slip and fall incidents.
These cases can involve unsafe conditions on residential, commercial, or other properties.
A successful premises-related claim typically depends heavily on the circumstances surrounding the dangerous condition and the property owner's responsibility for addressing it.
The firm's attorneys can investigate evidence, evaluate liability, and pursue appropriate compensation when negligence contributed to an injury.
Wrongful Death
O’Keeffe O’Brien Lyson Attorneys also represents families in wrongful death matters.
A wrongful death claim can arise when negligence or wrongful conduct causes a person's death.
Such cases may originate from motor vehicle crashes, medical malpractice, defective products, dangerous property conditions, or other serious accidents.
Wrongful death representation requires careful attention to both legal and personal considerations because families are dealing with significant financial consequences while grieving the loss of a loved one.
Family Law Services
Family law is another major pillar of the firm's practice.
O’Keeffe O’Brien Lyson Attorneys provides representation involving:
-
Divorce
-
Collaborative divorce
-
Child custody
-
Parenting time and visitation
-
Child support
-
Adoption
-
Paternity
-
Grandparents' rights
-
Guardianships and conservatorships
-
Domestic violence matters
-
Protection orders
-
Name changes
-
Deprivation and termination proceedings
The family law team includes attorneys with substantial experience practicing in North Dakota and Minnesota.
Divorce Representation
Divorce can involve far more than simply ending a marriage.
Clients may need to resolve questions involving property, finances, children, support, and future parenting arrangements.
The firm's divorce lawyers assist clients with both conventional divorce proceedings and negotiated resolutions.
A particularly noteworthy service is Collaborative Law.
Collaborative divorce provides qualifying couples with an alternative approach to resolving their differences without relying entirely on traditional adversarial litigation. Attorneys Tracy Lyson and Tasha Gahner list collaborative law among their practice areas.
This gives clients another option when both parties want to work toward a structured negotiated resolution.
Child Custody, Parenting Time and Child Support
The family law attorneys also represent parents in disputes concerning what North Dakota terminology may describe as residential responsibility, custody, and parenting time.
These cases can involve disagreements over:
-
Where children primarily live
-
Parenting schedules
-
Decision-making
-
Visitation
-
Child support
-
Modifications of previous arrangements
Because custody disputes can have lasting effects on children and parents, experienced family law representation can help clients understand their rights and available options.
Adoption and Paternity
O’Keeffe O’Brien Lyson Attorneys also assists families with adoptions and paternity matters.
Adoption involves detailed legal procedures designed to establish permanent parental rights.
Paternity proceedings can affect parental rights, custody, parenting time, and child support.
The availability of these services makes the firm's family practice broader than one focused exclusively on divorce.
Criminal Defense
O’Keeffe O’Brien Lyson Attorneys maintains an established criminal defense practice representing people facing both serious and less serious criminal allegations.
The firm's criminal defense services include:
-
Felonies
-
Misdemeanors
-
Drug crimes
-
Property crimes
-
DUI/DWI
-
Administrative hearings
-
Protection orders
-
Assault matters
-
Juvenile cases
The criminal defense team includes attorneys with experience practicing in state and federal courts.
DUI and DWI Defense
Driving under the influence cases are specifically identified among the firm's criminal services.
A DUI or DWI matter can potentially affect driving privileges, employment, finances, insurance costs, and a person's criminal record.
The firm's lawyers represent clients during criminal proceedings and related administrative matters.
Their work may include examining the circumstances of the traffic stop, reviewing evidence, identifying potential legal defenses, negotiating where appropriate, and representing clients in court.
Felonies, Misdemeanors and Drug Offenses
The firm represents clients accused of both felony and misdemeanor offenses.
It also specifically handles drug and property crimes.
Criminal charges can carry substantial consequences, making early legal representation important when a client is under investigation or has already been formally charged.
O’Keeffe O’Brien Lyson Attorneys' criminal team works to protect clients' procedural and constitutional rights while developing a defense strategy based on the specific allegations and available evidence.
Real Estate Law
Real estate is another substantial area of the firm's practice.
The real estate attorneys have experience with both residential and commercial property matters.
Services include:
-
Buying and selling residential property
-
Buying and selling commercial property
-
Title reviews
-
Title disputes
-
Contract creation
-
Contract disputes
-
Easements
-
Rights of way
-
Access disputes
-
Transfer of title and ownership
-
Boundary disputes
-
Property liens
The firm can therefore assist with both transactional real estate work and disputes that arise after property ownership or contractual issues become contested.
Residential and Commercial Transactions
Real estate transactions involve significant financial commitments.
The firm's lawyers assist clients with contract drafting and review, title issues, ownership transfers, and other legal aspects of purchasing or selling property.
Its experience extends from relatively straightforward residential title examinations to complex commercial real estate transactions.
This makes the real estate practice relevant to homeowners as well as investors and businesses.
Title, Boundary and Easement Disputes
Property disagreements can arise over ownership, boundaries, access rights, easements, and liens.
O’Keeffe O’Brien Lyson Attorneys represents clients in these disputes and assists with resolving questions that can directly affect a property's ownership, use, or value.
This combination of transactional and litigation experience is a notable advantage of the firm's real estate department.
Business Litigation
Business litigation completes the firm's five principal practice categories.
O’Keeffe O’Brien Lyson Attorneys describes business litigation broadly as resolving non-criminal disputes between individuals and organizations, whether through negotiation or the court system.
Its listed services include matters involving:
-
Contracts
-
Corporations and LLCs
-
Partnerships
-
Real estate
-
Buy/sell agreements
-
Powers of attorney
-
Banking law
-
Mineral rights
Individual attorney profiles also show experience with civil litigation, foreclosures, collections, landlord-tenant disputes, and employment lawsuits.
Contract and Commercial Disputes
Contracts are central to business relationships, and disagreements about contractual obligations can create expensive disputes.
The firm's litigation attorneys can help businesses and individuals evaluate agreements, understand their legal rights, negotiate resolutions, or proceed through litigation when necessary.
The firm's broader real estate and business knowledge may be especially useful when disputes involve overlapping commercial and property issues.
Foreclosures, Collections and Landlord-Tenant Matters
The business litigation team also handles matters involving foreclosures, collections, and landlord-tenant disputes.
These services broaden the firm's commercial practice beyond large corporate lawsuits and make it relevant to local property owners, creditors, landlords, and businesses dealing with everyday civil disputes.
Strengths of O’Keeffe O’Brien Lyson Attorneys
One of the firm's greatest strengths is its multidisciplinary structure.
Instead of concentrating on only one legal niche, O’Keeffe O’Brien Lyson Attorneys has dedicated attorneys working across personal injury, family law, criminal defense, real estate, and business litigation.
Its regional knowledge is another advantage. The firm is deeply focused on North Dakota and Minnesota, while its personal injury lawyers also handle matters across South Dakota.
The legal team includes attorneys with experience in state and federal courts, transactional matters, negotiated settlements, and litigation.
The firm's lawyers have also received professional recognition. Attorneys including Tim O’Keeffe and Tatum O’Brien have previously been recognized by Super Lawyers, while other team members have received professional and community-related recognition.
Potential Limitations
The firm's regional concentration can also be a limitation for some prospective clients.
O’Keeffe O’Brien Lyson Attorneys primarily serves North Dakota and Minnesota, with some attorneys also licensed or practicing in South Dakota and federal courts. Someone with a legal matter arising far outside these jurisdictions should confirm whether the firm can provide representation.
The practice also does not prominently advertise several areas offered by some full-service firms, such as immigration, bankruptcy, tax planning, or intellectual property registration.
Clients needing highly specialized services outside the firm's listed practice areas may therefore need different counsel.
Who Should Consider O’Keeffe O’Brien Lyson Attorneys?
The firm may be particularly suitable for:
-
People injured in car or motorcycle accidents
-
Families dealing with catastrophic injuries or wrongful death
-
Medical malpractice victims
-
Consumers injured by defective products
-
People considering divorce
-
Parents facing custody or child support disputes
-
Families pursuing adoption

Individuals charged with DUI, felonies, misdemeanors, or drug offenses
-
Homeowners buying or selling property

Commercial real estate investors

Property owners involved in title or boundary disputes

Landlords, creditors, and other parties facing civil disputes

Client Reviews
7 reviews"Tasha was my attorney for the last year through a very nasty custody battle with my ex-wife. During court the proceedings, communication, professionalism, preparedness , and knowledge of the law are key. Tasha kept in constant communication with us both with email and teams and telephone. I didn’t get to work with anybody else within the office, but if they are even half as amazing as Tasha was, I would not hesitate to retain any of them for any legal matter. It is true what they say you get what you pay for, personally, I feel like I got a hell of a bargain with Tasha. Tasha, if you’re reading this, thank you again for everything you’ve done and helping us win our case, and we’re definitely going to keep you on retainer!"
"I was very lost and vulnerable when seeking help for a divorce. Tasha Gahner showed a level of empathy and patience that I didn’t think was possible. Throughout the process, I genuinely felt heard, understood, fully represented, and empowered. She was so down-to-earth and there to help me, something I truly valued."
"We can’t say enough good things about our experience with Tasha Gahner. She made a stressful situation seem manageable, was always quick with responses, and guided us through the process step by step. She listened and was able to find common ground to meet all our goals. We would recommend her to anyone."
"I was delighted that they represented me for my daughter's legal name change. They worked very quickly, and in less than two months I had the results. I highly recommend them."
"Have met a couple of times with Brandon and feel very comfortable working with him for our living will and estate planning. He explains things in words that we can understand!"
"Great place and great people! I was recommended through a friend's mom that used this law firm years ago. Tasha was very understanding of the situation I was in, and she did a great job representing me. Would recommend her to anyone in family situations. Thanks again!"
"Was referred here through Legalshield. Handled my child custody case. Tasha G was extremely informative and handled everything very well. We were able to settle everything through mediation and I even got some of my retainer back in the end. I couldn't have asked for a better lawyer or firm to help me through such a difficult process."

Write a ReviewFrequently Asked Questions
Our legal team represents clients across North Dakota, South Dakota, and Minnesota. We have extensive experience navigating the specific legal systems of these three states, providing expert counsel to individuals and families who have suffered as a result of accidents, medical malpractice, or other negligent acts.
A catastrophic injury refers to severe, life-altering, or permanent damage that results in long-term physical or mental impairment. These cases—such as Traumatic Brain Injuries (TBI) – often require lifelong medical care and significantly impact a person’s ability to perform daily activities. Because these injuries affect families for decades, we provide a high level of expertise to ensure rightful compensation for long-term care.
Medical malpractice occurs when a healthcare professional fails to comply with established safety regulations, resulting in a preventable mistake that causes injury or death. Since thousands of people are affected by medical errors annually, our firm works to determine if a physician’s negligence violated the safety standards meant to protect you, helping you secure the justice you deserve.
While no amount of compensation can relieve the pain of losing a loved one, our compassionate attorneys help alleviate the resulting financial burden. We fight to secure compensation for the family’s loss and seek justice for the deceased, handling the “challenging and arduous” legal process so the family can focus on healing.
Our experienced family law team serves clients throughout both North Dakota and Minnesota. We specifically provide professional guidance for individuals and families in the Fargo and Moorhead areas, as well as the surrounding communities in both states.
Adoption laws are not universal; they vary significantly between North Dakota and Minnesota. By working with an attorney well-versed in the specific statutes of both states, you can ensure that all legal requirements are met—whether you are filing for an adoption or placing a child for adoption—to prevent any future legal complications.
These agreements act as clear contracts that define property ownership, spousal support, and other legal rights in the event of divorce or the death of one of the spouses during the marriage period. By establishing these terms ahead of time—or even after marriage—couples can significantly reduce unnecessary legal costs and time spent in court should a separation or divorce occur in the future.
Establishing paternity is often a critical first step for many other legal actions. Once paternity is legally confirmed, it opens the door for a knowledgeable attorney to help you secure or understand your rights and responsibilities regarding child custody, child support, and parenting time.
