Les Wallerstein

I am an attorney with a master’s degree in psychology, committed to the least adversarial practice of law possible. I had 20 years of experience working as a psychotherapist with individuals, couples, families and groups before becoming a lawyer in 1990.

I served as president of the Massachusetts Council on Family Mediation in 2001, and was the founder and editor of MCFM’s Family Mediation Quarterly from 2002 – 2013. I have been certified as a divorce mediator by MCFM since 1996.

In 2000 I was a founding member of the Massachusetts Collaborative Law Council, and served as treasurer for two years. Between 2003 and 2006 I was a co-founder and co-editor of MCLC’s Collaborative Law Journal, and have helped teach collaborative law.

My family practice has always concentrated on mediating agreements. In 1996 I stopped representing plaintiffs or defendants in court. I believe it is especially important to avoid the ravages of litigation when children are involved whenever possible.

I still represent clients in adversarial actions as settlement counsel. Our work focuses exclusively on negotiating agreements. When a mediated or collaborative agreement is not possible, I refer clients to lawyers who specialize in litigation.

While collaborative legal representation is an integral part of my work, mediating family disputes remains at the heart of my practice.
