If you find yourself needing legal help in the Boston area, give this firm & Attorney Manchinton a call. The entire firm was very supportive and responsive throughout my entire case. I could tell Attorney Manchinton genuinely cared and felt a sense of indignation about what I was going through. We were able to get the best possible outcome - a dismissal at the clerk magistrate level which was such a relief. Don’t hesitate, don’t call someone else, hire the Law Office of Matthew W. Peterson.Posted on MikeTrustindex verifies that the original source of the review is Google. Matt and team were very professional and helped me understand everything.
