Highly Recommend Jason Grosky

I had the pleasure of working with Jason Grosky during a particularly challenging time, and I cannot speak highly enough of his counsel. Though my case never proceeded to trial, Jason's guidance throughout the process was invaluable. He was knowledgeable, responsive, and consistently demonstrated a c...lear command of criminal defense law. Jason kept me informed at every stage, answered my questions with patience and clarity, and always made me feel that my case was a priority. I am grateful for his expertise and would not hesitate to recommend him to anyone in need of a skilled and dedicated criminal defense attorney.

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!

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.

I won both of my cases with Jason Grosky and couldn't recommend him more.

Jason Grosky was my attorney for 2 separate cases and made a difficult time in my life that much easier because he truly cares about his clients. The first matter involved violations of court orders where I was a victim, and the last case concerned a gun charge alleged against myself. The gun charge ...was dismissed without any charges being formally filed, I won both of my cases due to his efforts and attention to detail. Most importantly, his ability to tell your story is what sets him apart. I would highly recommend Jason Grosky as it's rare to find a lawyer with both a high competence to win your case as well as genuinely care about you as a person. To have people like Jason in your corner during difficult times made all the difference for me.
