Karl A. Borgsmiller

St. Louis, MO | D 314.571.4971 | F 314.256.2549

Karl Borgsmiller focuses his practice on complex civil litigation.

Karl works on national and local defense teams representing clients ranging from small businesses to Fortune 500 companies in state and federal courts throughout the United States. He assists clients in cases involving mass tort and product liability, medical and pharmaceutical liability, premises liability, commercial motor vehicle accidents, and commercial litigation.

Karl’s experience includes fact investigation, discovery, responding to and preparing pleadings, conducting depositions, dispositive motions, and trial preparation. In each case, he studies every available resource to understand the legal issue at hand and gain insight into the client’s business in order to obtain optimal results.

During law school, Karl was a law clerk for Federal Magistrate Judge Abbie Crites-Leoni of the U.S. District Court for the Eastern District of Missouri. In this role, he evaluated pleadings and motions filed with the court, prepared opinions, and observed all aspects of civil and criminal federal litigation – an experience that continues to influence his federal practice today.

Passionate about giving back to his community, Karl regularly assists clients in pro bono landlord-tenant disputes as a volunteer attorney for Legal Services of Eastern Missouri.

In his free time, Karl enjoys attending concerts, traveling to sunny beaches, and spending time with his family. A former Division I track athlete, he loves to play sports – especially soccer and basketball. He also likes to camp and hike in Missouri’s beautiful state parks.
