About me

      My focus is on family law, collaborative law, divorce mediation, and care and protection matters. I believe that family law is the most important and rewarding area of law in which a lawyer can practice. It is also an area of law in which clients need experienced, skilled, and compassionate representation to help them navigate the process.


I have practiced law for over 23 years and I am admitted to the bar in both Massachusetts and New York. In addition to family law, my background includes experience in landlord/tenant, real estate and intellectual property matters (focus on artists, museums and non-profits). In 2001, I was formally trained as a mediator.


I am a Co-Chair of the Metro West Collaborative Law Practice Group, a member of the Massachusetts Collaborative Law Council, the Massachusetts Council for Family Mediation, the Massachusetts Bar Association, and the Massachusetts Juvenile Bar Association. I graduated from Whittier College School of Law (J.D.) and Boston University (B.S.). I am ardently committed to working with my clients to help them achieve their goals and objectives.

  • Rackham Karlsson

    Because Cindy and I have co-mediated together, I have had a chance to observe first-hand her ability to guide clients through both difficult financial topics and challenging emotional exchanges. She has all the hallmarks of a skilled and experienced mediator, and I endorse her wholeheartedly.

  • Ann Sullivan

    I'm happy to recommend Cynthia as a first rate, experienced mediator. I first met her when she mediated cases in which I represented clients. Subsequently I co-mediated cases with her. Cynthia skillfully helps the parties identify the key issues in their dispute and assists them in generating options for resolving them. Using her intelligence, experience and compassion for people trying to resolve difficult issues, she creates an atmosphere in which dispute resolution is possible.
