Teamsters Union 25 Health Services & Insurance Plan
Founded in 1955, the Teamsters Union 25 Health Services & Insurance Plan emerged from collective bargaining between Boston's Teamsters Local 25 and participating employers. It is a multi-employer, jointly trusteed plan under Section 501(c)(9) of the Internal Revenue Code. The Board includes an equal number of union and employer representatives, co-chaired by Thomas G. Mari of the union and Michael Shaughnessy of Shaughnessy & Ahern Co. The plan's mandate is narrow: it provides medical, dental, vision, pharmacy, and hearing benefits exclusively to eligible Local 25 members and their families. The fund's investment portfolio is estimated at $301 million (Altss estimate). Its strategy is classified as growth-oriented. The plan deploys capital primarily through third-party benefit partners — Blue Cross Blue Shield for medical, Express Scripts for pharmacy, and Davis Vision — but it also directly owns and operates a network of clinical real estate. Its balance sheet includes a headquarters and major clinic at 529 Main Street in Charlestown, a standalone pharmacy next door, and clinical facilities in Chelmsford and Stoughton. The property portfolio also extends to land holdings, including parcels on Main Street and Mishawum Street in Charlestown. The plan is administered by a small professional staff led by Executive Director Maria Gnerre. It maintains clinical operations across at least four Massachusetts locations, offering in-house audiology, dentistry, behavioral health, and pharmacy services. The fund is closely tied to the broader Teamsters ecosystem: it affiliates with Teamsters Joint Council 10 New England and partners with the New England Teamsters Federal Credit Union. Its philanthropic arms include the Teamsters Local 25 Autism Fund, a holiday toy drive, and a scholarship fund. May 2026: The plan promoted wellness initiatives including an AHealthyMe video-quiz program and a Healthy Vision Month campaign. What separates the Teamsters 25 plan from a standard Taft-Hartley fund is its integrated clinical service model. Instead of purely outsourcing care, it operates brick-and-mortar treatment centers and a pharmacy directly on its Charlestown campus, giving trustees a dual role as both healthcare financiers and direct care providers for 18,000 plan participants.
