Denver Personal Injury Lawyer Colorado

Dedicated to Our Clients

“I became a lawyer to help others and it remains my calling in life. In fighting for victims’ rights, we side with the underdogs — the people who were injured due to someone else’s negligence. I’m very proud of the relationships I build with my clients and for the lasting impact of the work we do on their behalf.”

~ Scott O’Sullivan

“Immediately at ease.”

My wife and I interviewed other lawyers and they all made us uncomfortable. Scott put us at ease immediately. The way he handled the situation, the way he talked to us… he calmed us down. I knew I had to have surgery and go through rehab. Scott said, ‘Let me take care of the legal side of your case and your hospital bills and you just focus on getting better.’ Scott got my medical bills reduced. I still don’t know how he did it but I know that he did a lot of work behind the scenes.

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.


Our Promise To You

If you work with The O’Sullivan Law Firm, I promise:

At my firm, you will always work with an attorney and an attorney will always be in charge of your case. We have excellent paralegals supporting our attorneys’ work, but only an attorney — in consultation with you — should make decisions regarding your case.

In order to understand the full extent of your injuries and the legal ramifications of your auto accident or motorcycle accident, your attorney must take time – often a lot of time – to understand your case. You will get our undivided attention.

If a personal injury attorney simply looks at your insurance and the other driver’s insurance to determine the potential value of your case, then he’s not doing his job. There are many, many sources that may be available to you given the details of your unique case. Again, these can only be discovered by an attorney who is willing to listen and to spend time with you on your case. I will be that attorney for you.

Most people become lawyers because they want to help people. Sometimes, however, they get pulled into giant law firm machines that are more concerned about their bottom lines than their clients. You should seek an attorney who is still connected to the reasons that he or she went to law school in the first place: to help people.
