Daniel L. Rosenthal

Dan is a litigator with extensive experience in a broad range of business and commercial matters. Dan’s cases have involved too many areas of law and industries to list here, but they have included corporate fiduciary duties, implied warranties, franchise relationships, employment issues, railroad laws and practices, commercial leases, insurance coverage and constitutional issues — enough variety to keep him on his toes. Dan’s clients range from Fortune 500 companies to small businesses and individuals, and he has advocated for those clients in federal and state trial and appellate courts, as well as in administrative tribunals and arbitration. Recognizing that not all cases should be tried, Dan has also helped bring dozens of cases to an agreed-upon resolution through mediation.

A significant element of Dan’s practice has been representing of automobile manufacturers in recurring franchise litigation with dealers.  Dan has also handled franchise and dealership issues in a number of other industries.

Before joining Marcus Clegg in 2010, Dan was a partner in a large Portland law firm, where he had practiced since 1998 and served as Chair of the firm’s Trial Department.  From 1997 to 1998, Dan served as a law clerk to then-Chief Judge Ronald R. Lagueux of the United States District Court for the District of Rhode Island.

Dan is the author of a chapter on discovery depositions in the volume, “A Practical Guide to Discovery and Depositions in Maine” (MCLE 2014), and he has served as a continuing legal education presenter on trial evidence and objections.  He also served as a member of the Civil Process Improvement Stakeholders Working Group created by the Maine Supreme Judicial Court to study and provide input on proposed changes to the Maine Rules of Civil Procedure.  He is rated “AV Preeminent” by Martindale-Hubbell, has been named a “Super Lawyer” and has been selected for inclusion in the Benchmark Litigation guide, which is based on interviews with attorneys and clients.

A lifelong musician, Dan is a member of the Board of Directors of 317 Main, a nonprofit community music center located in Yarmouth, Maine. He sees as many shows as his schedule allows. He is a lifelong Red Sox, Bruins and Patriots fan who remembers the ugly years, and skis all winter regardless of whether there is any snow.
