Jason Lien focuses his litigation practice on representing clients from the construction, real estate, financial services, food, and railroad industries. He regularly appears in federal and state court on behalf of design-build firms, general contractors, architects, engineers, specialty contractors, property management companies, real estate owners, and lenders. A portion of Jason's practice also involves representing a major U.S. railroad in disputes throughout Minnesota and North Dakota.

Recognized by Chambers USA for construction law in 2016-2021, he is described as "an esteemed trial lawyer with a wealth of experience assisting with litigation mandates relating to construction defects and insurance coverage issues." Prior to joining Maslon in 2002, Jason honed his trial and appellate skills as a Naval Officer with the United States Navy Judge Advocate General's Corps, where he led hundreds of courts-martial, administrative hearings, and military appeals.

In addition to his litigation practice, Jason served as a member of Maslon's Governance Committee from 2017-2019 and as the committee's vice chair from 2018-2019. Jason was selected for inclusion on the 2015-2019 Minnesota Super Lawyers® lists and prior to that was recognized on the Minnesota Rising Stars lists.

Outside of the office, Jason is an avid triathlete and a two-time Ironman finisher.
