Description of Practice

I have been a divorce mediator for over 30 years.

Professional Background

In 1998, after having worked as a family law attorney and mediator at Hemenway & Barnes for 14 years, I formed the law firm of Ginsburg & Leshin, LLC. I transitioned my practice in 2021 from Ginsburg & Leshin, LLC to becoming Of Counsel at the law firm of Goldman & Sidgwick, LLP


Over the past thirty years I have mediated hundreds of divorces; many involving complex financial issues. I have also served as a conciliator, arbitrator, and case evaluator. I am in the process of expanding my practice as a neutral to providing services as a facilitator and ombuds.

I approach mediation as a facilitative process; not evaluative. As the need arises, I will provide couples with options of how to resolve particular issues. And, as well, I can provide couples with the "shadow of the law" -- sometimes rather clear, sometimes rather diffuse -- in service of helping them find a resolution of the issues they need to address. I pride myself on being empathic and concise. Through three decades of practice, I am able to help couples navigate complex financial and parenting issues. If juggernauts arise, I offer couples the option of transitioning to a five-way process with lawyers participating


My hourly rate is $485 and, absent any unusual circumstance, would request a $5,000 retainer.

Other Information

I am the proud recipient of the 2013 John Adams Fiske Award for Excellence in Mediation presented annually by the Massachusetts Council on Family Mediation (MCFM). For over 20 years I have authored "The Massachusetts Family Law Sourcebook" for MCLE. This year I am delighted to co-author it with Attorney Gina Calabro, of Brick, Jones, McBrien & Hickey, LLP. Over the past 3 decades I have lectured on tax, mediation and family law issues for MCFM, Massachusetts Continuing Legal Education, Boston Bar Association, Mediation Works, Inc., Community Dispute Settlement Center, Suffolk University Law School, Boston College Law School and Boston University School of Law. I am fluent in French and Dutch.
