Teirney S. Christenson is the current managing partner of Yost & Baill’s Wisconsin office. In that capacity, Teirney oversees a talented team of attorneys, paralegals and legal assistants who are devoted to working with Yost & Baill’s clients to develop the best possible strategy for each individual subrogation claim.  Teirney focuses his practice on catastrophic losses throughout the United States involving defective products, construction defects, breach of warranty, breach of contract and tort claims, including claims arising from subrogation, contribution and indemnification.

Teirney began his legal career gaining invaluable trial experience at a law firm in Milwaukee, where he assisted clients with complex litigation in state and federal courts, including product liability, personal injury and construction defect cases. Prior to that, Teirney received his juris doctorate degree from the University of Wisconsin Law School, where he learned to enjoy legal research and writing as a Note & Comment Editor for the Wisconsin Law Review and penned Fish on Morphine: Protecting Wisconsin’s Natural Resources Through a Comprehensive Plan for Proper Disposal of Pharmaceuticals, 2008 Wis. L. Rev. 141, which was awarded the Wisconsin State Bar Environmental Law Essay Award.

While earning his bachelor’s degree (magna cum laude) at Belmont University in Nashville, Teirney worked part-time as a barista, where he developed an appreciation for the word “y’all” and a palate for a good shot of espresso. You will rarely find him without a cup of coffee in his hand. When he’s not taking depositions, negotiating settlements or preparing cases for trial, you can find Teirney headlining local musical festivals or playing weddings with his band, Tallboy. His favorite people in the world are his wife, Leah, and his children, Kaydence, Quincey and Iloe. Quincey has loved coffee from his first sip (at age 2).
