Jim began his practice with the Massachusetts Department of Labor & Industries handling prevailing wage rate enforcement and public construction bid protests. He moved to the Associated General Contractors of Mass. Inc. in 1977 and was named its Executive Director in 1981. He joined John D. O’Reilly, III in July 1986 and formed the firm of O’Reilly and Grosso.

Jim represents the major construction industry employer associations in New England, including the negotiation of their collective bargaining agreements with seven different labor unions. He represents individual employers, including international construction firms, in dispute resolution procedures including mediation and arbitration and appears before the National Labor Relations Board regularly. Jim is counsel to several Taft-Hartley pension, health and annuity funds in New England advising clients on compliance with the Employee Retirement Income Security Act (ERISA), the Pension Protection Act (PPA), the Health Insurance Portability and Accountability Act (HIPAA) and the Affordable Care Act (ACA).   On behalf of the Commonwealth of Massachusetts, he negotiated Project Labor Agreements for all construction at the University of Massachusetts Boston Campus, the Longfellow and Whittier Bridge Projects and The Route 91 Viaduct. He has also negotiated Project Labor Agreements in the private sector for large pharmaceutical companies including Bristol Myers Squibb and Novartis and for The Gillette Stadium.  While his practice is centered in the construction industry, he also represents clients in the trucking and energy industries.

Jim has represented clients before the United States District Courts in Connecticut, Maine, Massachusetts and Rhode Island and in the Chancery Court of New Jersey. He has appeared several times before the First Circuit Court of Appeals and has tried numerous jury cases in the superior courts of Massachusetts in both employment discrimination matters and construction claim litigation. He has also participated in multiple arbitrations to resolve collective bargaining disputes.  He regularly engages in mediation to settle civil litigation and has served as an impartial arbitrator in commercial cases.
