About Us

Since 1986, Dempsey Kingsland Osteen has stood as the leading authority in medical malpractice, catastrophic personal injury, and wrongful death litigation throughout Kansas City and surrounding regions. Our firm's foundation rests upon a relentless commitment to justice for those who have suffered grievous harm due to the negligence of healthcare providers, employers, and manufacturers. We combine decades of courtroom experience with an in-house team of medical experts-physicians, surgeons, and nurses-who bring invaluable insights to each case. This synergy empowers us to dissect complex medical records, uncover hidden evidence, and articulate clear, compelling arguments for our clients.

Our attorneys-Sydney Dowell, Robert Kingsland, Jason Osteen, Leland Dempsey, and Diane Plantz-are seasoned litigators known for their strategic acumen, compassionate client care, and a track record of securing substantial recoveries. From the first consultation to trial or settlement, we prioritize open communication, transparency, and a personalized approach that respects the emotional toll of each case. Clients can rely on our downtown Kansas City offices, which feature ample parking and flexible scheduling, including evenings and weekends. For those unable to travel, we are ready to meet at home or in hospital rooms.

We take a no-fee-unless-we-win policy, ensuring that financial barriers do not prevent individuals from seeking the compensation they deserve. Our firm's dedication to the injured and their families has earned us widespread recognition from both the legal community and the public. We are proud to have recovered millions of dollars for our clients, including landmark settlements exceeding $100million in cases involving vaccine injuries, medication errors, and catastrophic surgical failures.

At Dempsey Kingsland Osteen, every client is treated with dignity, respect, and a relentless pursuit of justice. Contact us for a free consultation and discover how our expertise can help restore your life and secure the future you and your loved ones deserve.
