Metropolitan Mediation Services (MMS) is an innovative organization which has offered mediation services in the Greater Boston area since 1984. MMS provides mediation services to businesses, government agencies, schools, courts, social service agencies, and individuals from Greater Boston neighborhoods and families. We also provide conflict resolution training to business people, attorneys, judges, mental health professionals and educators, among many others. MMS mediators and trainers have a wealth of experience, training, and education in mediation and conflict resolution. MMS has a multi-disciplinary staff which includes attorneys, social workers, and educators from elementary through graduate level. Metropolitan Mediation Services offers a variety of dispute resolution programs and services, including:

Mediations at MMS are informal conversations with the help of third party, neutral mediators. 

Mediation by MMS is free. 

MMS coordinates a meeting time and place accessible to the participants and invites the participants to attend. 

Participation is voluntary. 

At the mediation, participants are invited to hear one each other’s concerns and perspectives directly from one another and see if they can use the opportunity to move in an agreeable direction which helps to resolve the dispute.  Generally, mediators begin with everyone speaking and listening to one another together in the same room.  Sometimes, if the mediator feels it would be of service, the mediators might meet with each side privately.  The mediators do not decide either who is right or wrong, nor what should happen.  We hope this voluntary opportunity will serve the interests of all the participants. 

Confidentiality is the spirit and practice in mediation by MMS, and is protected by statute (MGL Ch. 233, s. 23C) and, in court referred matters, by the SJC Uniform Rules on Dispute Resolution.
