Wonderful experience !

I hired Jason to help with obtaining a restraining order for my son against another classmate after years of bullying with both physical and verbal issues. Jason was quick to respond to all my questions , extremely knowledgeable with how these orders worked and what was necessary for a successful ou...tcome. In addition, my son is autistic- he has high functioning autism . Jason was great speaking to him , walking him through how court would go and reassuring him that he would be there to guide him through his questioning . Ultimately, Jason was able to get the outcome we had hoped for and my son never had to physically enter the courtroom . I’m extremely grateful for his help, professionalism and patience .

Your Go to Lawyer!

My husband and I had never needed a lawyer or been through the court system before, so we felt completely lost. Hiring Jason was one of the best decisions we made. He was incredibly responsive, patient, and always took the time to answer our many questions without ever making us feel like a burden. ... My husband was served with a restraining order that was completely unfounded. Throughout the hearing, Jason demonstrated exceptional judgment and strategy. He knew exactly which questions to ask and how much pressure to apply without overdoing it. His ability to read the room and navigate the situation was impressive. Thanks to his skill and professionalism, the restraining order was dismissed, and my husband can move forward without it on his record. Jason is knowledgeable, approachable, and easy to talk to. While I hope we never need legal services again, he would be my first call if we did. Highly recommend. Thank you, Jason!

Best in the business

If you need a defense attorney, call Jason Grosky! He went above and beyond and facilitated everything for me. He knows the process and the system and is on your side from day one. I was more than happy with the outcome and I would call him again if need be.

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.
