Very committed and skilled attorney

Mr.Grosky represented me in a case in which I was looking at significant time. He did this pro bono. He was extremely professional in every way. When we first met to go over the case he was very thorough in collecting all my info. He did not rush at all and gave me the definite sense that he really c...ared. At my ball hearing he spoke atleast twice as long as the da and really put forth a great case for my release. After that he arranged a very very good plea deal for me which allowed my release from jail much sooner than expected. Even after his job was done he sent me an email offering his advice for what I should and shouldn't do once out. This was not necessary but he did it because he really cares. Mr. Grosky is a phenomenal lawyer that I cannot speak highly enough of.

Exceptional Attorney

Jason Grosky is an exceptionally experienced, dedicated, and driven attorney. I came to Jason on a recommendation from a coworker who spoke just as highly of him as I now do. My case involved a driving incident with a Class A Misdemeanor charge, carrying the possibility of a large fine, potential ...jail time, and a lengthy license suspension. After submitting a brief explanation through the Grosky Law Firm website, Jason emailed me the very next day to schedule a consultation and gather the necessary information. I showed up to that meeting in a panic, already without a license due to a quick suspension. By the end of the consultation, most of my worries were gone—Jason explained everything clearly, outlined the potential outcomes, and gave me a step-by-step plan moving forward. Once I hired him, Jason immediately put his years of experience as a prosecuting attorney to work. He secured me an expedited DMV hearing, assuring me that he would handle everything. While awaiting that decision and with a court date still months away, Jason reached out to the arresting officer, identified weaknesses in the case, and negotiated a plea deal. The result: my charge was reduced to a simple traffic violation with a $100 fine, no criminal record, and a joint request to the DMV for my license reinstatement. Instead of facing months of uncertainty, I had my license back and my case resolved well before my scheduled court date. Throughout the entire process, Jason was reassuring, responsive, and professional—rarely taking more than an hour to reply to emails or texts, often responding within minutes. I cannot recommend Grosky Law Firm enough!

Excellent

Jason Grosky represented my daughter in a potential criminal case involving driving. From the time we first met with him, everything was explained in great detail, and in easy to understand language which put her at ease. She knew what to expect at every step. The end result turned out in the best po...ssible outcome, leaving her with no record. I have already recommended Jason to other people. He was awesome! I highly recommend him!

Grosky is the best you can get. Seriously.

I hired Attorney Grosky to represent me on two Misdemeanor A theft charges in Salem District Court, and he exceeded my expectations in every way. Jason's communication was exceptional - always responsive, clear, and thorough. He explained my options and potential consequences in terms I could unders...tand, and developed a strategy to protect my record. His courtroom advocacy resulted in the best possible outcome: a continuation without a finding (CWOF) for both charges, meaning they'll be dismissed in two years with no criminal record if I comply with reasonable conditions. What impressed me most was his attention to detail and genuine care for my future. He provided comprehensive documentation of everything filed with the court and clear guidance about next steps, including how to annul the charges after dismissal. His professionalism and dedication made a stressful situation manageable. If you're facing criminal charges and need an attorney who will fight for the best outcome while keeping you fully informed, I cannot recommend Jason Grosky highly enough. He truly made all the difference in protecting my future.

Jason Grosky will Litteraly fight for your best outcome!

Let's start with the main point and that is flat out Jason Grosky is the best attorney I've ever met or had. I had a court date on April 16 of 2025. I had a schedule 1 possession charge hanging over my head. When I walked in to court on that morning I had no lawyer and no idea how much trouble I was... in. I knew i would be given a court appointed attorney, and to be honest I didn't have much faith. As I sat in court I watched as the many attorneys walk in. Then Jason Grosky walked in. This guy just seemed different, he had a certain charisma about him. I said to myself "I hope I get that guy". Sure enough I did, and right from start line he was business. Jason let me know what the court was asking for, and informed me that he would like more time to go over my file. By the time I got home I had a full email from Jason explaining the police report and what would be the smartest andnext step. Jason kept in touch with me leading up to our next court date. He kept me informed and gave me his personal cell if i had an questions,and i did, he picked up every time. That brings us to May for my next court date. Right away Jason had me text him when I arrived. Shortly after there he was. He explained what the court was gonna ask for, and made me clearly understand that he was gonna fight to get the best possible outcome. I didn't know if I was going to get a little time or what. Jason pulled me in the back office and explained that they wanted a one year probationary term. Jason got that down to 6 months. I asked Jason what would our best possible outcome, and he informed me that would be administrative probation. He said that probably might not happen but he would try anyway. As I waited to re-enter the court I got a tap on the shoulder, it was Jason and he said "Administrative " I answered "are you serious" and he said "yup".Just to be clear the court originally wanted One year probation, and Jason fought and got me 6 Months administrative probation. He explained every detail about my probation and made sure I understood. To be completely honest working with Jason felt like having one of your best friends fighting for your freedom. Thanks for Everything Jason. I plan on staying out of trouble but if something happened Jason would be the first person I call.
