President Carol O'Brien

On behalf of the Ohio Prosecuting Attorneys Association let me welcome you to our website.  Here you will find information about the role of prosecuting attorneys and our Association.

The prosecutor’s role in the criminal justice system is often misunderstood.  Ohio’s 88 elected county prosecutors are committed to justice.  The prosecutors I know aren’t motivated by “winning” or trying to send everyone to prison for as long as possible. They are motivated by their responsibility to enforce the law, to make their communities safe and to fairly administer justice. And fairness and justice is what matters most of all.  Prosecutors live this every day.

Part of our role is to have a voice in public policy debates affecting the criminal justice system. To that end, Ohio’s prosecutors serve an important function reviewing and advocating for legislation with one goal in mind – the safety and security of our communities.

Ohio’s prosecutors are active in community and civic affairs.  From speaking to school children about the dangers of drugs to serving on numerous committees and commissions, Ohio’s elected prosecutors and their assistants serve in vital roles.

As legal counsel to a variety of County elected officials, offices and agencies your county prosecutor assists in ensuring efficient and responsible county government. 

I’m proud to be a prosecutor and honored to serve as President of the Ohio Prosecuting Attorneys Association.  Please take your time and look around.  Hopefully you will find information here that is educational and informative about your county prosecutor.
