They are the best. always call and give u updates on cases and treat u like familyPosted on Google N MaceusTrustindex verifies that the original source of the review is Google. I am an attorney and a registered nurse, and I hold professionals to a high standard. Matthew Peterson exceeded every one of them. I retained him seven days before a contested 209A restraining order hearing — from out of state, with a record thousands of pages deep and an active case in another jurisdiction layered on top. Seven days is not much time. He made it look like plenty. He read everything; I know because within a day his questions were sharper than mine. He built the strategy, moved fast, and kept me informed in plain English at every step. His entire office works the same way — I sent materials at one in the morning and had a substantive reply before lunch. Not once did I wonder where my case stood. In the courtroom he was everything you want: prepared, precise, composed, and completely in command of the record. The order was dismissed at the return hearing. What set him apart was not just skill — it was judgment and decency. He understood what was actually at stake for my family and treated it with the seriousness it deserved, without ever losing his calm. He told me the truth, including when it was hard, and then he delivered. If you need a restraining order defense attorney in Massachusetts, hire Matthew Peterson. I say that as a client and as a fellow lawyer: he was everything I could have asked for, and more. Five stars is the ceiling on this form. He earned more.Posted on Google PrinceTrustindex verifies that the original source of the review is Google. I come to realize there's no perfect review but a review written from a place of honesty.
