Douglas J. Mac Arthur, Attorney


Douglas Mac Arthur practices primarily in construction law, helping construction industry stakeholders with dispute resolution, litigation, contract drafting, negotiation, and insurance coverage matters. He also defends contractors and other companies against citations from OSHA, MnOSHA, and other similar regulatory agencies, including arguing an appeal to the Minnesota Occupational Safety and Health Review Board.

Doug has a strong background in the construction industry, including a B.S. in Construction Management and almost ten years as a remodeling contractor. Prior to joining Moss & Barnett, Doug practiced construction law with a law firm representing and advising general contractors, construction managers, subcontractors, developers, architects, and engineers in transactions and disputes involving residential buildings and developments, commercial projects, and industrial buildings. Prior to that, he worked under the general counsel of a large Minneapolis general contractor where he gained exposure to many legal and business matters. In addition, Doug served as a judicial extern for Minnesota Fourth Judicial District Court Judges Denise Reilly and Laurie Miller. This prior experience gives Doug a unique perspective on what is important to a company and its owners.
