Jason Poss

Jason Poss’ practice focuses on the defense of medical, legal, and financial professionals, as well as employment and general liability defense. He is admitted to practice in Oregon and Washington.

Before joining Hart Wagner in 2014, Jason worked at two smaller civil litigation firms in Portland, where he defended personal injury, construction defect, product liability, and general liability cases.  During that time, he also gained invaluable experience from a plaintiff’s perspective, managing a high-volume caseload of automobile, commercial, and workers’ compensation subrogation claims.

Jason earned his law degree from University of Oregon School of Law in 2010.  While attending law school, he served as a research assistant to Professor Suzanne Rowe, contributing to the publication of three legal research texts.  He was also named the top editor on his law review by his peers.  Jason obtained his bachelor’s degree in business management from University of Iowa in 2006, graduating with honors.

Jason spends his free time with his wife, Jackie; their two young children; and their poorly-trained golden retriever.  He also serves on the Board of Directors of Adaptive Sports Northwest, a local nonprofit that promotes recreational, fitness, and competitive opportunities for children and adults with physical disabilities.
