Jon-Jamison Hill is a partner in M&R’s Los Angeles office and a member of the firm’s Commercial & Business Litigation Practice Group. Over the past two-plus decades, he has compiled an extraordinary record of success litigating cases no matter the venue—federal and state courts nationwide, as well as at arbitration and mediation.

Having handled single-party and class action cases across industries—banking and financial services, entertainment and sports, technology, and construction, to name a few—Jon’s experience spans the breadth of commercial and business litigation. Among his areas of expertise are disputes arising out of contracts, construction defects, intellectual property, real estate, trade secrets, groundwater contamination, professional responsibility, and complex public works construction projects. Jon’s work extends to the appellate court level as well, and some clients seek his counsel in major transactions, specifically, to provide the guidance necessary to help them avoid litigation and resulting financial exposure in the event a given deal fails or otherwise falls through.
