About Me

I have over twenty years experience in Criminal/OVI law, seven years as a veteran prosecutor and thirteen years as a top defense attorney.  A charter member of the renowned "four horseman" defense firm of Callahan, Greven, Rilley and Sinn,  I have learned and earned the skills to win. I travel all around the Northeast Ohio area representing good people who find themselves facing down the police and government in tough situations. I handle everything from drunk driving cases (OVI/DUI) to Capital Murder. I'm very good at my job and I work hard for my clients. If you have a legal problem in Akron, Barberton, Bedford, Stow, Ravenna, Kent, Massillon, Canton, Parma, Wadsworth or anywhere else in Northeast Ohio, give me a call. My consultation is free and I will do my best to help you. Call or text me at 330-431-0160. You will speak to me and I will tell it like it is so you can make smart decisions about your future. My consultation is free so give me a call. 


P.S. "google" any lawyer your considering. Search "jon sinn ohio attorney" and check me out.

    An exceptional attorney. Hard working, extremely bright, and first rate. He ranks at the top in his field. I have worked with him on cases, and would do so again without any hesitation. Without question, he is among the very best.

    I endorse this lawyer. Jon is the busiest attorney in town, and the reason why is because he is a great attorney! He genuinely cares about his clients and always treats them with respect. He gets along with everyone in the court system, but if need be, he is a fighter. He is tough, but kind. He is not just a great attorney, he is a wonderful person, he would give you the shirt off his back. I consider him a mentor, and I have learned a lot from him.
