In addition, Marjorie serves as a mediator. 

Marjorie represents clients in the Massachusetts state courts, including frequent appearances in the Business Litigation Session of the Massachusetts Superior Court, in the United States District Courts in Massachusetts, California and Connecticut, and before arbitral panels, including the International Court of Arbitration.  She has also represented clients pro hac vice in litigation matters in other jurisdictions throughout the United States, including New York, Texas, Illinois, Ohio, Florida, Virginia, Rhode Island, New Hampshire, Alabama, Mississippi, West Virginia, Montana, Georgia, Maine, and Maryland.

Representative Matters

    • Marjorie defended a national law firm sued by a former client for malpractice in connection with its handling of litigation between the founders of a start-up company.  Following a 3-week trial, Marjorie obtained a jury verdict for her client as well as judgment in its favor on its counterclaim for payment of unpaid attorneys’ fees.
    •  Marjorie successfully defended a real estate company against an effort to terminate its property management contract for one of Boston’s premier office towers.  She tried the case to a judge in the Business Litigation Session of the Massachusetts Superior Court, winning a judgment on all counts.
    •  Marjorie defended a member of senior management of a national securities company in multi-district class action litigation alleging “market timing” violations of the Securities Exchange Act of 1934.  She obtained a ruling in her client’s favor on a Motion to Dismiss and the plaintiffs then voluntarily dismissed the sole remaining claim against him.
    •  When Marjorie’s client, the owner of retail gasoline stations, was sued by the owners of adjacent property for environmental contamination, she tried to case to a jury, winning a very favorable verdict for her client. 
    • Marjorie represented an international manufacturing company which brought an action seeking a declaratory judgment that it had not terminated, repudiated or breached two complex agreements for the design and construction of two co-generation power plants in Louisiana.  The case was resolved very favorably through a unique process of binding mediation, developed to address the parties’ needs in the context of that case.
