Personal injury attorneys

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

At The O’Sullivan Law Firm, we focus solely on personal injury law, it’s all we do. We realize that injured people need an advocate on their side during the most difficult time of their lives. Someone who always works for their best interests and understands the legal, medical, and financial challenges they may be facing.

Our Promise to You

Our Denver personal injury attorneys provide accident victims with one-on-one, personalized attention and dedicate the time and resources necessary to be successful in every case we take.

There is a big difference between The O’Sullivan Law Firm and those large firms that advertise all over your television – and it has nothing to do with the price you pay. It has to do with the way we treat our clients and the results we get.  We make a promise to every client we represent:

  • An attorney will handle your case, not a “case manager” or a paralegal.
  • We will take time with you and listen.  We want to understand your story and every detail of your case.
  • We will seek every opportunity to secure your rights.  We leave no stone unturned when seeking the compensation you deserve.

The O’Sullivan Law Firm has achieved a 99% success rate, which we attribute to the promise we make to every client.

If you or a loved one have been injured in a Colorado accident, contact us today to discuss your case – for free. Our attorneys will gladly meet you in your home, at the hospital, or any place that makes the most sense for your life right now.

Real clients. Real results.

Practice Areas

Swift Action is Vital in Personal Injury Cases

After a serious injury, it is important that you speak with an attorney as soon as possible. At The O’Sullivan Law Firm, we begin working on our clients’ cases immediately. We collect evidence, contact witnesses, file paperwork, and help our clients get the medical attention they need. The longer you wait, the more time insurance companies have to devalue or deny your claim completely.

Additionally, there are time limits involved in personal injury claims known as the Statute of Limitations.  If you fail to file a lawsuit within them, you may lose the opportunity altogether.  Having a personal injury attorney on your side is the best way to ensure that all deadlines are met and your claim remains valid.
