Posted on Noah LynchTrustindex verifies that the original source of the review is Google. I cannot say enough good things about Attorney Matthew Peterson. I’ve had the privilege of working with him over the past 13 months, and throughout that entire time he has been nothing short of exceptional. Matthew is extremely knowledgeable, thorough, and strategic, but what truly sets him apart is how invested he is in his clients. He took the time to fully understand my situation, explained every step of the process clearly, and always made sure I felt informed and prepared. Even during stressful or uncertain moments, he remained calm, responsive, and professional, which gave me a great deal of confidence. His communication was outstanding — prompt, honest, and straightforward — and he never made me feel rushed or dismissed. It was clear from day one that he genuinely cares about achieving the best possible outcome for his clients, not just closing a case. If you are looking for an attorney who is sharp, dedicated, and truly has your best interests at heart, I highly recommend Attorney Matthew Peterson. Working with him over the past year plus has made a difficult process far more manageable, and I’m extremely grateful for his guidance and support.Posted on Jason Hinton IITrustindex verifies that the original source of the review is Google. Mr.Peterson and his entire staff were incredibly helpful, with best intentions always in mind I got caught in an unfortunate situation while bringing my LEGAL firearm in my home state (Florida) to Massachusetts, and got the book thrown at me for possession related charges. Originally I was facing 4 felonies and 3 misdemeanors from the situation After some time Mr.peterson got the DA’s office to drop 2/4 felonies and reduce 1 felony to a misdemeanor before we even got to the pre-trial negotiations So I was then facing 1 felony, and 3 misdemeanors, after some more time he got the DA to accept a plea for me to get 1 year of probation and the final felony thrown out. So all and all 4/4 felonies got dropped and I got a CWOF so once I complete my year of probation I will have nothing on my record at all. Side note, Mr. Peterson and his team are still actively working to get my $1,500 hand gun returned to me (the police have had it since the night they took it) If you do find yourself in a bad situation, I couldn’t recommend attorney Peterson, and his team enough, I know I’ve said it a lot to you personally Mr Peterson but genuinely from the bottom of my heart I greatly appreciate the time and effort you and your entire team put into my case, and I hope that eventually Massachusetts will choose to be pro 2A so law abiding citizens like myself don’t get caught in unfortunate interstate gun situations.Posted on Miles KleinTrustindex verifies that the original source of the review is Google. I had the privilege of working with Attorney Chris O’Brien. The process was highly collaborative, and I was kept informed every step of the way.
