  • Profile


Dennis R. Lansdowne has been with the Spangenberg firm since 1985 and has been a partner since 1990. During that time he has represented individuals in catastrophic injury and wrongful death cases as well as large corporations. "My background and training have allowed me to pursue cases for both people and businesses that have suffered harm. It is an interesting and exciting practice."

Dennis graduated summa cum laude from Cleveland-Marshall College of Law, where he was a member of the Law Review. Following graduation, he served as a law clerk to the Honorable Robert B. Krupansky at both the Northern District of Ohio and the Sixth Circuit Court of Appeals. "Working in both the trial and appellate courts gave me a unique opportunity to see the litigation process and I was fortunate to observe many fine lawyers from Ohio and other parts of the country. I knew I wanted to devote myself to that process and practice at the highest level."

Pursuing Justice for Victims of Medical Malpractice

Dennis has represented hundreds of people who have been seriously injured or lost a loved one because of the negligence of a doctor, nurse, nursing home, or another healthcare worker. He is well-known for being able to make complex medicine easy for a jury to understand.

The National Institute of Medicine has estimated that 280,000 Americans are killed in hospitals because of negligence every year.

That is four times the number killed in automobile crashes. The vast majority of these deaths do not result in a lawsuit, many times because the families aren't aware that negligence has occurred. "The sad fact is, we don't have too many malpractice lawsuits. We have too few." Dennis's passion about medical negligence led him to create and teach a course on the subject for several years at his alma mater, Cleveland-Marshall College of Law.

He has remained involved with the law school and is a past president of the alumni association and a current member of the school's advisory council for the health law and policy center. He has also had the distinguished honor of being the recipient of the 2013 Alumnus of the Year Award given by Cleveland-Marshall College of law for outstanding professional achievement, leadership and service to the community.

Insurance Companies- An Industry in Need of Reform

When an insured pays premiums, sometimes year after year, they expect the coverage they paid for. Too often the claim is met with delay and denial. Dennis has represented insureds, from individuals to large corporations, in order to force the insurance company to honor its promises. All of the insurance cases handled by the Spangenberg firm are done on a contingency fee basis. "The contingency fee is attractive for individual clients, but we have found that businesses can also benefit from this type of fee arrangement."
