Firm Overview

A Tradition of Excellence; a Record of Success

The law firm has never wavered in our commitment to provide high quality - high value legal services. Our firm has offices in Boston and Quincy and serves clients throughout Massachusetts.


Our tradition of excellence began when the firm opened the doors at 803 Hancock Street in Quincy, Massachusetts. Martin Cosgrove had already been working with Francis X. Bellotti for five years. When Mr. Bellotti became Attorney General for the Commonwealth of Massachusetts in 1974, the law firm became known as the Law Offices of Martin S. Cosgrove, P.C. Joined in practice by Lewis C. Eisenberg and Thomas R. Kiley, the firm began operating as Cosgrove, Eisenberg & Kiley, P.C., in 1987.


Today we have nine attorneys focused on handling legal matters related to personal injuries, workers' compensation, family law, criminal defense, construction law, medical malpractice, business law, and political or election law. Our attorneys each focus on a specific legal area, while drawing on the skill and experience of the firm. This allows us to provide comprehensive legal representation on a wide range of legal matters.


Attorneys Martin Cosgrove, Lewis Eisenberg and Thomas Kiley have all been selected to the American College of Trial Attorneys, a prestigious organization which is limited to the top one percent of all trial attorneys in the United States. A vigorous review process is used to screen those recommended to the College. All our attorneys are skilled in dealing with politically sensitive issues, and are known for discretion when dealing with high-profile cases.

Our firm is involved in pro bono and charitable work in the communities that we serve in Quincy and Boston, such as anti-poverty organizations and other non-profits. Community involvement is important and we are committed to that effort. Some of the attorneys in the firm serve as officers or directors in some of these organizations or donate our legal services. The firm is a charter partner with the Law Firm and Corporate Partners Program of the Massachusetts Bar Foundation. Proud Partner Supporting legal Aid in Massachusetts

No matter what type of legal matter we are handling- construction law, elections law, or some other issue-our primary goal is to provide sound legal advice and personalized representation. We provide the information and explanations our clients need to make important decisions.
