Diane Plantz, JD, MD

Diane Plantz, JD, MD, joined Dempsey Kingsland Osteen’s medical malpractice litigation team in 2022. Prior to that, Diane practiced medicine for more than 20 years, with the last 12 years of her medical career at Children’s Mercy Hospital in Kansas City. Diane graduated from Vanderbilt University School of Medicine in 1994. She completed a pediatric residency at Mount Sinai Hospital in New York City and a pediatric emergency medicine fellowship at Cincinnati Children’s Hospital Medical Center. While serving as an attending physician in pediatric emergency medicine at the Children’s Hospital of Wisconsin in Milwaukee, Diane received her master's in bioethics from the Medical College of Wisconsin.

Diane moved to the Kansas City area in 2005 to work at Children’s Mercy Hospital. While at Children’s Mercy, she served on the ethics committee providing ethics consultation and hospital-wide ethics education. She also served on the research institutional review board. Diane has taught bioethics to residents, fellows, medical students, and graduate students, and developed one of the first international online pediatric bioethics programs. It was her passion for bioethics, where medicine and law intersect, that Diane found her passion for law.

After practicing medicine for more than 20 years, Diane decided to pursue this passion, and in 2015, she began studying as a part-time law student at the University of Missouri-Kansas City School of Law, while working full-time in the emergency department at Children's Mercy. While in law school, she participated on the Client Interviewing Team and served on UMKC Law Review. In 2017, she decided to stop practicing medicine completely to dedicate herself to law. Upon graduation in 2018, Diane joined Shamberg, Johnson and Bergman, specializing in medical malpractice. In March 2022, she joined Dempsey Kingsland Osteen.

When Diane was a physician, she advocated for her patients—going to great lengths to promote their best interests. As a medical malpractice attorney, Diane still feels like a patient advocate—fighting for individual patients and their families who have been harmed by the health care system.
