Scott was my attorney on a personal injury case and after years of waiting for the criminal side to finish, he stuck with me through the entire process. During the criminal proceedings he was always in constant contact with the DA to make sure the cases would not interfere with each other. He was always available to answer my questions and even once his part in the case was complete, he has always taken the time to talk to me when issues came up with the collection of the judgement that we were awarded. For the past 7 years he has been continually supportive through the process, helped keep me standing when the case would emotionally drain me and has always been a contact for any further issues with the judgement (long after his part in the case was completed). I am so grateful to have had such a caring attorney to work with through the hell of the case and constantly reassure me that it was going to be ok.

I was involved in an accident while I was commuting home on my bicycle. A car ignored a red light and t-boned me at a busy intersection, leaving me injured and without a bike. I heard about Scott O’Sullivan after he came to my work to answer questions for our cycling group. I didn’t need his services at the time, but after this accident, I immediately thought to call his law firm and I’m glad that I did. I primarily worked with Melissa Hemmert and Sharon of the firm and they were very helpful throughout the entire process. I met with their team for the initial consultation and they gave me clear advice on how to handle my situation. Once this was complete, they took care of the rest. If I had questions, or just wanted a status update on my case, they were quick to answer my emails. The at-fault driver’s insurance company refused to budge on a settlement offer, but Melissa kept fighting for a fair settlement, and she got it for me. If you’re looking for an attorney, I would highly recommend the O’Sullivan Law Firm!

They handled my motorcycle accident, they really took care of me and my family. Scott and Eli really do care for their clients, and went above and beyond for us.

I don't know the outcome of my case yet. But, what I wanted to say is this, I came to their office, we talked about a lot of things, but one thing I figured for myself that they are honest people. They do the right thing and I know from my life experience that when you do the right thing, things always work out for the best. They are not that type of people, I think who would do anything and everything just for the money. Which is why they won my heart. And it is very important who you working with on your claim, I believe. There are plenty of law firms in the city, but I am glad that I came here and I have a good feeling that I did the right thing.

The O'Sullivan law firm team and Mr. O'sullivan did excellent in my auto injury case. I was hurt pretty badly by a negiglent driver and did not know what to do. Fortunate enough, I met him and his team and they got things done with my best interests. Ive had experience with other law firms and I got to say the staffs professionalism and strong effort to make things right was outstanding. I wish them the best in continuing stellar service for others in the community. Once again, thank you O'Sullivan Law Firm!

To Whom It May Concern: My name is Keith Muse; I retained Scott O'Sullivan to represent my interest in a lawsuit against a drunk driver. I met Scott by chance and after finding out he was an attorney I asked about my type of case. He made it clear he was not looking to take me away from my current attorney and then proceeded to tell me more about my case in 10 minutes than my current attorney had in 3 months. I promptly fired my former attorney and retained the services of the O'Sullivan Law Firm. I could not be happier with that decision. Scott and his entire firm showed the utmost care, consideration, dedication, professionalism, and genuine regard for me and my situation. The entire team worked diligently to move my case along without delay. They kept me informed and prepared every step of the way as the case moved forward. In the end, Scott skillfully negotiated a very favorable settlement. I have and will continue to recommend Scott and the O'Sullivan Law Firm to anyone needing legal representation. It is refreshing to see such a high level of honesty and integrity in today's world. I can not say enough positive things about my experience working with these good people. Sincerest Regards, Keith Muse

If you are ever injured in a car accident, the O'Sullivan Law Firm is your best choice as far as lawyers in Colorado. I didn't have much experience with lawyers, so I was shopping around to see which one would be the best fit for me. After going through a few choices, I found Scott and was very impressed with him and his firm. Amanda, Eli & Scott have worked SO hard to get my good results from this whole 3 year ordeal, and they are very stand up and honest people. It is hard to find that these days, and to know you can absolutely 100% trust your lawyer is a very relieving feeling, especially when dealing with something as messy as a car accident. I would recommend Scott's firm to anyone I know and have the reassurance that they would be in good hands. Thank you so much Amanda, Eli & Scott!!

I reached out to O’Sullivan Law Firm after firing a different firm that wasn’t representing me the best that they could. I was Involved in an auto accident and foremost, O’Sullivan wanted to make sure that I was made whole again. That included my health and my loss from the accident. My experience was excellent! I always felt comfortable and professionally represented. You can’t go wrong with hiring O’Sullivan. Believe me, don’t settle for subpar representation the big billboard attorneys have posted all around Denver Metro.

I talked to a lot of different lawyers and the o’Sullivan law firm was the one and only firm that treated me like a person instead of a number. A motorcycle accident is a very stressful time in anyone’s life so when you find a man like Scott O’Sullivan life becomes a lot easier!!!

I had a great experience with the O'Sullivan Law Firm, and specifically with Eli Ohlhausen. Eli was helpful, courteous, and professional. He was willing to do whatever was required, and he was particularly excellent at communicating with me regularly and updating me on what was going on. I would highly recommend this firm to anybody.

Having an auto accident can put you in a horrible position. You will never be able to recover completely without the help of a trustworthy law firm. O'Sullivan is just the type of firm that will be there for you not only on a law level, but a personal level as well. My experience with them gave me the power to go forward without worry. They will let you know exactly what you need to do. On top of that, they actually care about what happens after everything is taken care of. Don't go with some large law firm you see on TV promising everything under the sun. Go with these kind, caring people because they will really take care of you. It's been 3 years since my accident and even today I feel like I picked the right people. Thank you Scott for everything you, Eli Ohlhausen and your people did for me.

They took my motorcycle injury case even though it wasn’t a sure thing and eventually won me a settlement. Scott and Eli took personal attention and kept me informed along the way. Scott even came to speak at my bike club on his own time regarding legal matters relating to bikers. Very satisfied with my experience and definitely recommend.

I have had the unfortunate experience of being involved in two very serious car accidents. I was referred to the O'Sullivan Law Firm by a good friend and I am extremely grateful for the referral. Eli is an exceptional lawyer who guided me through extremely difficult times. I could could count on Eli to answer all my questions and concerns as well as counsel me when I needed the emotional support to get through this traumatic period of my life. I am grateful to Eli and the O'Sullivan Law Firm for all the support they gave me during these cases and going to bat for me to get me the compensation I rightfully deserved.

I was injured in a car accident. I contacted O'Sullivan law and was introduced to Eli and Kathy who are extremely professional, knowledgeable and very thorough. Since my recovery included several surgeries they made sure I knew what to expect and what the next steps would be. They were very patient with me when I had none and we're genuinely concerned about the hardships this had put me through. We were able to settle my case and I would recommend Eli and his team to anyone who is in need of legal help.

Everyone I worked with at O'Sullivan was great. They took the time to explain everything and made the whole process much less intimidating. They provided regular updates and made sure I was well compensated. I hope I never need them again, but if I do I won't hesitate to call.

Choosing the O’Sullivan Law Firm turned out to be one of the best decisions we ever made. After our car accident in a span of six months my husband and I had experienced three different attorneys that all failed to make us feel we were being represented with our best interest in mind. Attorneys Scott, Cara and their caring team of professionals worked diligently to prove our case while assuring us our personhood was being respected, as well as our health and injuries were being handled with care! After a long three year battle our case was won! I recommend the Sullivan Law Firm to anyone who needs a personal injury/accident lawyer. We thank the Sullivan Law Firm for all their hard work and assuring our case was justified! Meeting you was a blessing!

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!
