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!

Best Experience

Jason took great care of my elderly dad. His communication was clear and understandable and he went above and beyond to see his case through, closing it out successfully and faster than we anticipated. As with any issue involving an attorney, the experience can be stressful and scary, but Jason const...antly stayed in communication with us and assured my Dad he would be just fine. Many thanks! Hopefully we don’t need his services again, but if we do, Jason will be the first to get a phone call.

Simply the best!

Jason’s professionalism, expertise, and genuine care for his clients are truly unmatched. He assisted me with a personal matter and resolved the issue promptly and effectively. Throughout a challenging time marked by personal trauma, Jason made my safety his priority. He was always available to answe...r my questions, whether through text or phone calls, and never made me feel anything less than important during our interactions. What truly stood out was Jason’s ability to resolve my case through a mutual agreement with the other party, avoiding the need for a lengthy and stressful traditional hearing. His dedication and skill made a significant difference, and I couldn’t recommend him more highly. Thank you, Jason, for everything. Wishing you continued success!

Don’t go it in your own. Hire a professional.

I recently retained Atorney Grosky to represent me as the defendant a stalking and no contact order. Since I knew that the complaint was baseless, I had thought about representing myself in the case. I am very glad that I didn’t! Jason was well versed in the matter and not only helped me manage th...e basics of requesting and attending the expedited hearing, he followed through and proved during his cross examination of the plaintiff that the burden off proof wasn’t met. To say that it wasn’t his first day at the rodeo is an understatement. He was well prepared, thorough, and professional all the way through. He explained how each step would work, what the potential outcomes could be, and made sure that all of the I’s were dotted and the T’s crossed. I will recommend him to anyone in need of criminal defense.
