We Can Help You

If you’re here, you have probably been in an accident. Or someone you love has suffered in an accident. First and foremost, I am sorry. I, too, have watched loved ones struggle after a tragic accident and I know it can be completely overwhelming to try to manage all of the doctors, hospitals, insurance companies and even the emotions you’re facing.

I can help you. My firm provides accident victims with one-on-one, personalized attention and, because of this, we get better results than those big firms you see all over town. Contact me to discuss your case – for free. I will gladly meet you in your home, at the hospital or anyplace that makes the most sense for your life right now.

Our Team of Lawyers Makes the Difference

Scott O'Sullivan

Scott W. O’Sullivan is founder of The O’Sullivan Law Firm. He previously worked as an insurance company lawyer but left because he hated the way insurance companies treated accident victims. In 1996, Scott decided to represent only injury victims and he has never looked back.

Eli Ohlhausen

While riding a motorcycle, Eli was injured due to another driver’s negligence. He hired an attorney who negotiated a good settlement of his claim and the process changed his life. Eli used his settlement to attend law school and has been fighting for accident victims ever since.

Cara New

Cara New has brought numerous lawsuits against some of the largest insurance companies in the country, resulting in many six-figure and even seven-figure recoveries for her clients.

What is a Contingency Fee?

If you are looking for an attorney to help you after an accident, you should know that there is a distinct difference between personal injury attorneys and other types of lawyers. Personal injury attorneys don’t charge you a dime for anything until after your case is settled. If you have met an attorney who charges you for a consultation or asks you to pay a “signing fee” to handle your case, run the other way!

Personal injury law is one legal specialty that works on a contingency fee, which is simply a fancy way of saying, “free until we win.” You should pay nothing to your personal injury attorney until he or she secures a settlement for you from your case. At that point, your attorney will recoup some costs and receive an agreed-upon percentage of your settlement.

And by the way, it’s free to call me up to discuss your case. I would enjoy the opportunity to hear what you’re facing and to offer my help.


We Get Results

We boast an over 99% success rate with our cases. Simply put: With The O’Sullivan Law Firm, you and your case receive both personalized attention and the absolute best outcome possible. And because we work on a contingency fee, you won’t pay us any more than you pay those other firms.

Client Testimonial

“It’s a good thing we contacted Scott. The guy who hit my girls’ car was driving a dealership car and he didn’t have his own insurance. The dealership only had the bare minimum insurance. Scott said, ‘I’m going to try to get your medical bills reduced and then get it all covered by insurance.’ And he did it! Scott found ways to get everything taken care of plus he got the girls some money for school.”

Denver Accident Map

It feels like Denver’s streets are getting more dangerous by the day. But, aside from weekday morning traffic reports, it can be hard to determine how dangerous and where the car crash hot-spots are. We wanted a way to view car accidents in Denver by type and location so that we could make better, safer decisions about our travel routes. So, we created the Denver Accident Map, which allows you to drill down by month (within the last 12 months) and all the way down to the intersection closest to where you live. Use it to keep your family safe!


The O'Sullivan Law Firm Resources

I don’t think there is a more confusing, frustrating or scary time than the journey you face after a serious car or motorcycle accident. Not only are you managing your injuries, doctors, hospital bills and the emotions that threaten to overwhelm you and your loved ones, but you also have to grapple with insurance companies – both yours and the other driver’s. I am here to discuss all of this with you – for free. Additionally, I maintain a robust Resources section on this website to help you in all aspects of car, scooter, pedestrian or motorcycle accidents, insurance, safety, advocacy and more.
