Great guy, Great attorney!

Before meeting Jason Grosky I was an anxious mess. I got myself in a mess that I had no idea what to do. After just one consultation with Jason not only was my anxiety gone but I had a good idea of what was going to happen with my case. He explained everything to me in an easy manner and did not c...onfuse me with legal terms. Jason acted like we were long time friends and made me feel comfortable. Honestly, I feel lucky that he was my attorney because of how comfortable he made me feel. On top of all of that, the day of the court date he again reviewed everything with me and told me exactly how everything was going to play out, so there were no surprises. This made me feel even more comfortable. Then, in the court room Jason was magical. I do not want to get into details but Jason did exactly what we went over and in the end he won the case for me. If you are reading this and wondering if you should hire Jason, I would tell you I highly recommend him. I cannot thank him enough for what he did for me. I feel blessed and grateful that I met Jason and was able to work with 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.

Great Lawyer

I had the pleasure of working with Jason Grosky, and I couldn't be more impressed with the level of service I received. From the start, he was incredibly accessible and always available to answer any questions I had. His efficiency in handling my case was remarkable—everything moved along smoothly, a...nd I felt well-informed every step of the way. His communication was clear and timely, making sure I never felt left in the dark about any updates. He approached my case with a high level of professionalism, but what truly set him apart was his understanding and empathy. He took the time to listen to my concerns and worked with me in a way that made me feel supported. I highly recommend Jason Grosky to anyone seeking legal assistance

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.
