In 1935, Martin O'Donoghue founded O'Donoghue & O'Donoghue as a union-side labor law firm. Since that time, the Firm has dedicated its practice to advancing the rights of working men and women locally in the Mid-Atlantic region and nationally across the United States. Over the years and decades, O'Donoghue & O'Donoghue LLP's labor practice has grown both in size and prestige so that the Firm is now one of the oldest and largest union-side labor law firms in the United States.


"The essence of trade unionism is social uplift. The labor movement has been the haven for the dispossessed, the despised, the neglected, the downtrodden, and the poor. (A. Philip Randolph)"

"The fight is never about grapes or lettuce. It is always about people. (Cesar Chavez)"

"With all their faults, trade unions have done more for humanity than any organization of men that ever existed. They have done more for decency, for honesty, for education, for the betterment of the race, for the developing of character in men, than any other association of men. (Clarence Darrow)"

The Firm's attorneys also represent these unions before the National Labor Relations Board, the Federal Labor Relations Authority and the Office of Compliance, as well as before a wide range of administrative agencies. The firm's extensive practice as general counsel to these international unions provides O'Donoghue attorneys with a close familiarity with the operations of international labor organizations and with the unique characteristics of individual labor organizations.
