About Bison Law Firm — Personal Injury Attorney Yukon OK

Bison Law Firm in Yukon, Oklahoma, takes only one type of case: personal injury. That exclusive focus — auto accidents, trucking crashes, slip-and-fall injuries, nursing home abuse, oil and gas injuries, medical malpractice, product liability, and wrongful death — means every attorney and every support staff member at 1609 Professional Circle is oriented around one goal: recovering full compensation for seriously injured Oklahomans. Mark Van Paasschen leads the team alongside attorneys John Alberts, Kirk Olson, Nathan Richter, Thomason James, and a support team that clients cite repeatedly for keeping them informed at every stage. People dealing with injuries in Canadian County and the Oklahoma City metro can also review personal injury lawyers in Oklahoma when evaluating their options.

Bison Law serves the western Oklahoma City suburbs from Yukon and handles claims across Canadian County, where Oklahoma City’s growth has driven significant commercial truck traffic and highway accident volume. The firm’s singular focus on personal injury means cases are not deprioritized in favor of other practice areas — every client is an injury client, and the firm’s resources reflect that.

What Clients Say

Clients describe Bison Law as honest and upfront in a profession where those words are rarely used. Mark Van Paasschen is praised for giving personal attention that larger firms skipped over — one client called after the biggest firms wouldn’t listen on the phone, and Bison took the case and communicated every step. Karen Brady receives consistent praise for her compassion and patience with clients who need to vent or ask the same question twice. The team recovered settlements even in cases where the at-fault driver carried minimal insurance coverage, which clients found impressive.

Frequently Asked Questions

How long do I have to file a personal injury claim in Oklahoma?

Oklahoma’s statute of limitations for most personal injury claims is two years from the date of injury under 12 O.S. §95. Missing this deadline permanently bars your right to compensation, so consulting an attorney promptly — especially when injuries are serious — is critical to preserving your claim.

What if the at-fault driver had little or no insurance in Oklahoma?

Oklahoma requires drivers to carry minimum liability coverage, but many drivers carry only the minimum or drive uninsured. Your own uninsured/underinsured motorist (UM/UIM) coverage may compensate you in these situations. A personal injury attorney can identify all available insurance sources, including the at-fault driver’s policy, your own UM/UIM coverage, and any umbrella policies that may apply.

Is Oklahoma a comparative fault state?

Yes. Oklahoma follows a modified comparative fault rule — you can recover damages as long as your share of fault is less than 51%. However, your recovery is reduced proportionally by your percentage of fault. If you are found 20% at fault for a $100,000 claim, you recover $80,000.

Mark and Karen are amazing!!! I felt genuinely cared for during my injury claim. Karen listened to me vent, without judgment about everything to include my personal issues. Their team kept me up to date on every step. I can’t recommend them enough! They are in your corner!

I had an exceptional experience with Bison Law Firm. From the initial consultation to the final settlement, Mark, Karen, and Stephanie were absolute professionals. Their expertise, compassion, and dedication to my Canadian County case were impressive and reassuring.

So I have been to a handful of lawyers in my time and I will say that the Bison Law firm has the friendliest workers/ lawyers. They made me feel very welcomed while at the same time gave me reassurance and direction on a legal matter I was hesitant to go through with. I have heard stories about lawyers and how rude they can be but not this place at all. Definitely a 5 star for law firms. The front desk woman was also very helpful and nice. Again customer service goes along way and this place is amazing. Highly recommend them.

Mark VonPossum and his staff were excellent to work with. He was very professional and proficient in handling my case. I highly recommend using his office

Bison Law kept me updated with all updates. They were able to get me a settlement even when the person who caused the accidents had little insurance. They were patient with the questions asked. They answered questions my husband asked without becoming frustrated. If you want honesty, integrity, hire Bison Law.

This place is absolutely great. They are honest and upfront which is rare . They really do have the client interest before their own. Definitely recommend

Mark and Karen are great! They were both professional and compassionate towards my situation. They were always available to answer questions in detail and kept me updated on my case’s progress.

Extremely pleased with this firm. The bigger firms weren’t listening to my story over the phone, and Mark gave me personal attention and fought for me. Communicated every step of the way, and responded promptly to any question. Couldn’t be more appreciative of how things turned out, and their assistance and expertise. Uber-professional, and attentive to smallest details. Karen was super personable. Thanks to every one at Bison Law Firm!

Honest and professional, I know it seems odd to describe a lawyer this way. At the time of the service the staff was very helpful and very professional. Even though I never got a phone call back as it was stated I would, this only happened one time. I will still give them five stars. I understand that being a lawyer is a time extensive profession. Litigation takes time. Be patient and expect good representation.

This firm is top tier! They are very attentive, they communicate well, and they get it done. Most of all they are on your side. I could not be any more grateful for the work that they have done and the support that they have offered my family. The kindness and gratitude that Mark has shown will forever be appreciated. Thank you Bison law.

Bison Law Firm is Awesome! They fight for you every step ,from beginning to end!

I was very impressed with the services I received from Bison Law Firm. After having an accident, the firm helped me take care of all of the difficulties that came with that. Thank you to Mark VanPaasschen and the team at Bison for helping me through this journey! Mark was always there to answer any questions I had and followed up quickly. It is clear that the team truly does care and was there to help me every step of the way.

I cannot speak highly enough about my experience working through one of the most difficult and unfortunate situations my family has had to navigate with the help of what felt and still feels like a family and a true team that is Bison Law Firm.

I could give zero Stars I would. Mark Van Paasschen is very unprofessional. I talked to him about my case and he never followed up with me. I had to call this man over 40 times just to get his attention and each time he told me he would call me back and never did, he waited almost two years before he told me that he declined my case. He wasted my time, the time I could of use trying to look for a new lawyer that with possibly take my case. I do not recommend this law firm!!!
