Jason A. Lien
Vice Chair of Firm Governance Committee

Jason Lien focuses his litigation practice on representing clients from the construction, real estate, financial services, and food industries. He also frequently represents policyholders in insurance coverage and bad faith disputes. The 2018 edition of Chambers USA names Jason as one of Minnesota's top construction lawyers and describes him as "an esteemed trial lawyer with a wealth of experience assisting with litigation mandates relating to construction defects and insurance coverage issues." Sources interviewed by Chambers USA deemed him to be "prepared, thoughtful, strategic and analytical." 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.

Jason 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. He has also litigated disputes involving product liability, insurance coverage, international trade, land use, business torts, unfair competition, intellectual property, healthcare fraud, non-compete agreements, and medical malpractice. 

In addition to his litigation practice, Jason serves as vice chair of the firm's Governance Committee. Jason was recognized by Chambers USA for construction law in 2016-2018. He was also selected for inclusion on the 2015-2018 Minnesota Super Lawyers® lists as well as the 2006-2009 and 2011-2012 Minnesota Rising Stars lists.

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