Highly professional and results-oriented

Jason was professional and extremely effective in helping me in my case involving harassment. He took the time to visit me at my home, understand my circumstances and stay on top of the case through some twists and turns. He knows the law, he knows the courts and he will work closely with you to get ...to the result you’re seeking. If you need assistance in a criminal or motor vehicle matter, or an order of protection, I highly recommend Jason Grosky.

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!
