Barry N. Chait, Esquire

Barry is our senior tax counsel. Barry brings 40 years of experience servicing small and large businesses as well as individuals. Barry considers himself like a holistic advisor, where he ensures that he knows and understands all aspects of the business as well as all family matters so he can properly advise to the question at hand.


Barry has worked at several large national accounting firms as well small firms where he learned his expertise. When asked, what is his expertise, he will tell you, whatever my client needs it to be. It is much easier to learn the tax code than it is to learn about the client. Each client is different, with unique needs and Barry ensures that he learns the needs of his clients. No client it too small and no client is too big. While in law school, he learned that the library has answers to questions and one needs to know how to ask the correct question and how to interpret the answer.


Barry volunteers a lot of his time serving on boards and advising nonprofits. Barry is past treasure of New England Chapter of the American Liver Foundation, Director and Treasurer to the Dave McGillivray Finish Strong Foundation, in charge of media for Christmas in the City, and founder of the Harpoon 5-miler benefiting the Angel Fund for ALS research. Through his passion of helping others, Barry has presented numerous seminars for nonprofits on board development, fundraising, and the new 990, which is no longer new. These seminars were presented by Massachusetts Lawyers Clearing House, the Boston Bar Association and Massachusetts Continuing Legal Education.


Barry has a BS in Finance from the University of Massachusetts, a law degree from New England School of Law and completed the Masters in Accounting Program at Northeastern University.


In his spare time, you can usually see Barry running around with his daughter and granddaughter. Barry is an avid sports fan, ran and completed the Boston Marathon 13 times, practices yoga and loves food.
