Largest Law Firms in Massachusetts
The largest law firms in Massachusetts employ more than 7,560 local lawyers in offices throughout the Bay State. The online version of this ranking expands beyond what appears in print; another 95 law offices are included in our digital rankings, in addition to the 50 featured in this week’s print edition. This week’s List marks a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 40-plus sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ’s footprint — this year alone. Information on The List was obtained through Boston Business Journal research or supplied by individual firms through questionnaires that BBJ could not independently verify. In case of ties, firms are ranked by total lawyers for all offices and then total firm employment. If ties remain, records are then listed alphabetically. Law firms that did not respond to the BBJ’s survey requests are included based on estimated attorney counts from the firm’s website. Data pertaining to “total employees (all offices)” for those firms was obtained from annual filings with the U.S. Department of Labor (covering the years 2022 or 2023 as noted). Inclusion on this year’s List required each firm to have a minimum of 4 Massachusetts lawyers, using the methodologies described above.
