And if I could give 10,000 stars I would. I was assisted by Attorney Margaret Petersen, who is an excellent, incredibly knowledgeable, compassionate, and diligent professional. The individuals at Matthew Peterson Law are top notch and I cannot say enough positive words about them.Posted on Google Michael McDonoughTrustindex verifies that the original source of the review is Google. I started my experience with Mathew Peterson law firm with attorney Chris Obrien. A exceptional lawyer who has continued to go above and beyond for me. I am now being represented by attorney Manchington. Also, a high class-stand up gentleman who you want up to bat for you! Although my legal issues are still on-going, I am confident in the team at Mathew Peterson law firm that will continue to work hard and diligently for me! Highly recommend to anyone in need of legal assistance.Posted on Google Alexis SanabriaTrustindex verifies that the original source of the review is Google. 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.

I had the pleasure of getting Attorney Manchinton to represent me at a Clerks Magistrate Hearing. I believe that helped turn this situation into a positive experience for myself.

I thank him and all those at the office that helped too!Posted on Google Yadira RiveraTrustindex verifies that the original source of the review is Google. Amazing experience with Attorney Petersen.
