He was extremely helpful in an immigration matter of mine. Thank you!Posted on 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.Posted on 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.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
