About me

I have over twenty years experience in Criminal/OVI law, the first seven years as a top prosecutor and the last fifteen as a hard hitting criminal defense attorney. Since 2001, "The law offices of Jonathan Sinn" has helped thousand of criminal and OVI clients and earned a reputation for winning when it counts.. I travel all around the greater Akron, Ohio area representing good people who find themselves in trouble. Half of my practice is focused on defending drunk driving cases (OVI/DUI)  and the other half is criminal law. 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 me at 330-931-4384 or text me at 330-431-0160. You can call or text anytime but sometimes I cant respond for a few hours as I spend alot of time in Court. I am accepting new cases and I want to talk to you. 


For clients facing major cases in need of a team of lawyers,  I am also a member of the powerhouse "four horseman" defense firm of Callahan, Greven, Rilley and Sinn and can call on those resources if the situation demands.

    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.
