Michael Leshin

I have been a divorce mediator for over 30 years.

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

ADR Experience

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
