Darina KulahaTrustindex verifies that the original source of the review is Google. Attorney Peterson is a highly knowledgeable lawyer and a pleasant person to work with. He was extremely helpful in an immigration matter of mine. Thank you! Sunny Daze413Trustindex verifies that the original source of the review is Google. I was arrested in March and held on a $200,000 bail—no bail bonds in Massachusetts, so you need real money. I didn’t have it, so I sat in jail facing mandatory minimums and heavy time. From day one, Attorney Matthew Peterson looked me in the eye and said, “Let me get you outta here and back to the free world.” He fought hard to get my bail lowered, and little by little, he knocked that $200k down—all the way to $7,500. After 9 months, he asked, “Can you pay that?” I said yes. He said, “You’ll be home.” And I was. He was always reachable. I could text him at 2 a.m. on a Saturday night and have a reply by Sunday. What lawyer do you know who answers on a Sunday? That alone tells you how serious he is. We prepped for trial, filed motions, had a full game plan. He was ready to destroy the first case—easy work for him. But the second charge was riskier, and I was facing real time. The state offered a plea that brought me way below the mandatory minimum. It gave me a shot at moving forward with my life. Matt told me, “I didn’t go to law school to take pleas—I fight trials. But this is your life, and I’ve got your back.” I decided to take the deal, and I don’t regret it. I didn’t walk away completely free—but I walked away with a future, and that’s because of him. If you’re ever in a serious legal situation in Massachusetts, don’t wait. Call Matthew Peterson. He’s a fighter, a strategist, and a real one. SimonTrustindex verifies that the original source of the review is Google. I had a great experience speaking with Elijah from the Law Office of Matthew W. Peterson. Elijah was incredibly friendly and easy to talk to. He took detailed notes about my case and went above and beyond by diligently pulling court records to better understand my situation. Although I ultimately did not proceed with the firm due to timing reasons, I truly appreciated the professionalism and care shown during our initial conversation. Elijah made a strong impression, and I wouldn’t hesitate to reach out to this office again in the future.

Que Dios lo bendiga siempre excelenticimo trabajo gracias abogado matthew w peterson infitas gracias 🙏🏼🙏🏼🙏🏼 Biker Girl Paradise (Dise)Trustindex verifies that the original source of the review is Google. Matthew is the man!! BLUF: After fighting through a 2-part, 2.5 year battle that 20 lawyers (no lie) said I’d lose, he won both my cases with dismissals! And though it was another fight, he got all my daddy’s bail money back too!! DETAILS (Worth the read): While passing through Boston on a month long motorcycle trip, I unexpectedly found myself in a pinch. After my public defender actually offended me with insults, was repeatedly unresponsive, gave weak defense options & said I was guilty, I knew I had to find someone else! My family & I retained Matthew Peterson and I’m still praising Jah for him 👏🏾 As I don't live in MA, I was unaware my state's gun permit would not suffice for traveling through Boston. Why they expect non-residents to get a Mass permit is beyond me… and reasoning. They could easily put it on the state sign, but its all about the money I guess. As a result of false accusations, assumptions about the person I am & an illegal search, I ended up going to jail for a week with 7 trumped up charges & multiple cases. FYI: MA doesn’t have bails bondsmen… You pay the whole thing, all them thousands... in person, in cash 😫 I literally interviewed 20 lawyers who all said I had a next to impossible case and most likely my life & everything I worked so hard for would go down the drain. But God aint no joke… He led us to Matthew who came out of nowhere with a defense that surprised the prosecutor, the cops… and me! Even the judge was heckling them 😅 Aside from winning, I had a very good experience with Matthew… He's not hoity toity, condescending, arrogant or judgmental. Instead he’s very down to earth, open to questions (lots) & takes feedback very well! Realizing the hell his clients are going through, he stays calm even when they flip out... they = me 🤦🏾♀️ sorry Matthew 😔 He’s not the cheapest but I'm here to tell you, he will fight like hell for you! And if you end up in a critical, life-altering situation like I did, he’s what you need & is worth every penny! I’m so grateful for Matthew & all his hard work, HalleluJAH!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
