Description of Practice

This Mediator is Certified
I have over 30 years experience as a litigator and mediator. I currently focus on helping individuals resolve their family disputes without going through the adversarial court process. I mediate agreements for divorce, separation, spousal support, child support, parenting plans,inter-family disputes and elder transitions. I also mediate and review pre-nuptial and post-nuptial agreements.

In addition, I coach individuals on the options and the process for getting a divorce in Massachusetts, including individuals who wish to represent themselves in family law matters with minimal assistance of an attorney. I also facilitate the resolution of disputes among work, community and neighborhood groups.

Professional Background

My specialties include Family Law, Landlord/Tenant, Consumer Protection, Anti-Discrimination and Reasonable Accommodations for Persons with Disabilities. I began practicing mediation in 1993 and volunteered at the Middlesex Mult-Door Courthouse after attending the Harvard Law School Program of Instruction for Lawyers in Negotiation and the basic mediation training at the Community Dispute Settlement Center (CDSC) in Cambridge, MA.
